Description

  The present invention relates to an electric tulip installed in a pachinko gaming machine.

  As is well known, the electric tulip has a pair of wing pieces that open and close to the winning opening that opens on the front surface of the mounting board, and always holds the left and right wing pieces in an upright state to maintain a closed posture. It makes it difficult to prevent or prevent the hit ball falling from the game board from entering, while energizing the solenoid as a driving source when receiving a release instruction signal, and pulling the plunger to retract the wing piece. It is converted to an open posture that tilts in the left-right direction, allowing the ball to jump in, and opening it wide to the left and right to make it easier to jump in and allow many winning balls to be received in a short time.

  In this electric tulip, a swing interlocking member is interposed between the two to convert the expansion / contraction movement of the plunger of the solenoid into an opening / closing movement by rotation of the wing piece. Then, the swing interlocking member is swung around the fixed support shaft in accordance with the expansion and contraction of the plunger, and the interlocking pin protruding from the back of the blade piece is moved up and down by this swinging to support the blade piece. With the shaft as a fulcrum, it is rotated in the left-right direction so as to open and close.

In general, the electric tulip is made of synthetic resin as a whole except for the solenoid, but the support shaft of the winglet that requires stability and strength of assembly, the fixed support shaft that supports the swing interlocking member, Normally, a metal shaft is used for the shaft connecting the solenoid plunger and the swing interlocking member and the interlocking pin connecting the swing interlocking member and the blade.
Among them, the support shaft of the blade piece, the fixed support shaft of the swing interlocking member, and the shaft connecting the plunger and the swing interlocking member are fulcrums during rotation, and stability is required. Therefore, the use of a metal shaft is suitable, and the metal shaft is less likely to become an obstacle in manufacturing because of the assembly of parts.

However, in order to provide a metal interlocking pin on the wing piece, it is possible to insert a metal shaft member into a hole provided in the wing piece and press-fit it, but in general, insert molding is performed in order to achieve strong fixation. Is normal. Therefore, a mold for insert molding in which an interlocking pin is implanted is prepared on the wing piece and is molded by this.
For this reason, there existed a problem that manufacturing cost became high compared with the single molding by a synthetic resin.
Of course, as for the interlocking pin, it has been proposed that this is made of synthetic resin and formed integrally when the blade piece is formed, and replaced with the use of a metal shaft material. Because of the strong push-up and push-down directly on the top and bottom, and the pressing force is added to fix the opening and closing posture, the synthetic resin interlocking pin is insufficient in strength, and there is a risk of being damaged and missing.

The strength required for this interlocking pin is the strength that can withstand the expansion and contraction motion of the solenoid plunger, as described above, but this solenoid's starting force is alleviated, reducing the burden on the interlocking pin. If it can, the strength can be reduced, and the use of the interlocking pin made of synthetic resin becomes possible.
As a method of alleviating the impact on the interlocking pin accompanying the expansion / contraction movement of the solenoid or reducing the load, it is sufficient that the impact force accompanying the expansion / contraction movement of the plunger can be absorbed on the side transmitting the interlocking pin. One method is to use an elastic body for the connecting part that engages the interlocking pin of the swing interlocking member, and when the interlocking pin stops swinging and then presses, the elasticity causes the connecting part to bend and impact. The method of absorbing is mentioned. For example, this is the method disclosed in the patent literature.
Japanese Patent Application Laid-Open No. 2002-263280, claims in the specification, paragraphs 0010, 0019 to 0024, and FIGS. 1, 2, 3, and 4 of the drawings.

The invention of the above-mentioned patent document 1 is a proposal for avoiding the movement of the left and right blades 4a and 4b from stopping when the ball is caught between the blade 4b, that is, the wing piece and the game nail 21, and the interlocking pin. Although not related to the strength, the use of an elastic body here alleviates the impact on the opening / closing rotation pins 4a1 and 4b1, that is, the interlocking pins, and reduces overload.
However, one problem in this case is that the parallel plates 3a and 3b, which are elastic bodies, must be assembled to the crank arms 5c1 and 5c2, that is, the swing interlocking member. Also, the elastic force of the parallel plate must be adjusted to an appropriate strength.
In particular, assembling the parallel plate to the crank arm is more troublesome than installing a metal shaft on the blade by insert molding or the like, which is disadvantageous for the purpose of lowering costs while increasing productivity. It will be a thing.

  In view of the above situation, the present invention can reduce the impact force on the interlocking pin of the wing piece caused by the strong driving force of the solenoid that opens and closes the left and right wing pieces, and can reduce the strength required of the interlocking pin, This is to improve the manufacturability of the blade piece. Furthermore, the present invention enables the above-described interlocking pin to be molded using a synthetic resin as a material so that it can be integrally formed at the same time as the manufacture of the blade piece, and is troublesome due to the conventional press fitting or insert molding of a metal shaft material. This eliminates the problem, easily manufactures highly accurate wing pieces, and improves the productivity of electric tulips.

  In order to achieve the above object, the present invention provides a swing range of a swing interlocking member that is swingable by a solenoid serving as a drive source in an electric tulip, and a blade piece that is opened and closed by the solenoid via the swing interlocking member. For example, when the solenoid is released, that is, when receiving a signal to open the blade, it is excited and the plunger is pulled in, just before the blade reaches the open position. When the plunger is extended by a spring contracted by solenoid demagnetization when returning the blade piece to the closed position when the blade piece is returned to the closed position, the extension operation of the plunger is stopped immediately before the blade piece reaches the closed position. Therefore, the operating range on the drive source side, that is, the solenoid side including the swing interlocking member is regulated, and the blade piece that rotates the load associated with the regulation of the operating range. Let's provide an electric tulip that avoids the load on the interlocking pin that is interposed between them, that is, avoids the strong impact force that occurs when stopping, and reduces the strength required for the interlocking pin. It is what.

Further, the features of the present invention will be described in detail. The present invention is a closed posture that stands up with a pivot that stands on the left and right of the winning opening that opens on the front surface of the mounting board, and an open posture that tilts in the left-right direction. a wing constituting a lateral pair into a preparative, the there behind the mounting substrate draws plunger when subjected to release instruction, a solenoid lengthening pull the plunger spring compressed state upon receiving the closure instruction, One end that swings with a fixed support shaft as a fulcrum is connected to the flanger, and the other swinging end faces the back of the wing piece and the push-up piece of the connecting piece formed on the swinging end and the pusher and a reciprocating connecting member for connecting with the interlocking pin was thrust put slipping engaged a projecting from the rear of the wing between the lower piece, the expansion and contraction movement of the plunger of the solenoid via the reciprocating connecting member An electric tube that communicates with the blade and opens and closes. In the lip, the wing piece is facing the two stoppers for regulating the opening and closing range by the abutment at the closed position the open position, the plunger or swinging linkage operates integrally with the励失magnetic one of its said solenoid any parts material while regulating individually the swing range of the opening and closing range as the swing interlocking member of the wing by the swinging range is confronted with two stoppers for restricting the swing interlocking member, said rocking An object of the present invention is to provide an electric tulip characterized in that a swinging range of a motion interlocking member is set smaller than an opening / closing range of the blade piece.

As described above, the solenoid in the electric tulip has a structure that transmits the expansion and contraction movement of the plunger to the wing piece via the swing interlocking member, and the plunger and the swing interlocking member are freely connected to each other via a shaft. As a single unit, the linear movement of the plunger is converted into a swinging motion around the fixed support shaft of the swing interlocking member.
Therefore, according to the present invention, in restricting the swing range of the swing interlocking member, in addition to directly limiting the swing range of the swing interlocking member itself, by restricting the range of expansion and contraction of the plunger, Alternatively, it is possible to substantially restrict the swing range of the swing interlocking member by restricting one of the swing ranges in the swing interlocking member and the other in the plunger. And either one can be selected.

On the other hand, the opening / closing range of the pair of left and right wing pieces is regulated with respect to the mounting substrate that supports the wing pieces.
The wing piece is actually pivotally attached to a support shaft that passes along the front-rear direction inside the pocket-shaped enclosure provided on the front surface of the mounting substrate, and is closed with the support shaft as a fulcrum. And the two postures provided on either the mounting board or the surrounding frame provided on the front surface of the mounting board. Each is held by colliding. The range of rotation between the closed position and the open position is determined by the collision at these two locations, and is set as a restriction point.

That is, the present invention is provided with means for regulating independent movement ranges on the solenoid side including the rocking interlocking member serving as the drive source and on the blade side that is opened and closed by the solenoid.
Then, the present invention provides a difference in size between the two independent regulating means, and the blade piece reaches the closed posture or the open posture due to this difference, and stops in order to maintain these postures. At that time, the load on the solenoid side, that is, the swing transmitted by the swing interlocking member is stopped, the interlocking pin is released from the expansion and contraction of the solenoid plunger acting via the swing interlocking member, and the load transmitted to the blade piece. I tried to get rid of.

  The solenoid is necessary as a starting means when the blade piece is converted to the open or closed posture, but when the blade piece reaches the open or closed posture, the blade piece needs to be an interlocking stop means of the solenoid or the swing interlocking member. Absent. From this point, the present invention individually regulates the range of motion on the drive source side and the range of motion on the side of the blade to reduce the impact force received when the blade is stopped. The load was reduced.

In order to cut off the driving force by the solenoid immediately before the blade pieces reach the two open / close positions, the swing range of the solenoid side, that is, the swing interlocking member, may be set smaller than the open / close range of the blade pieces. It becomes a condition. And, when the operation on the solenoid side is restricted and stopped, in order for the blade piece to independently rotate until it reaches its restriction point, the connection portion of the swing interlocking member and the interlock pin of the blade piece It is necessary to secure a gap between them.
The air gap is formed in each of the wing pieces when they are opened and closed, but the air gap itself is prepared to cut off the operation on the solenoid side, so that a direct contact state can be avoided. A small width is sufficient on the condition.

The left and right wing pieces are restricted on the solenoid side, that is, in an opening / closing range different from the swinging range of the swing interlocking member, and when opened and closed, the left and right blade pieces are independently held in an open posture and a closed posture. In order to stably maintain the state, in the present invention, the center of gravity is positioned above the support shaft and positioned in the middle of the opening / closing range.
As a result, in the present invention, when the position of the center of gravity rotates beyond the perpendicular passing through the support shaft by the rotation of the blade, the center of gravity moves in the direction beyond the perpendicular and then automatically rotates in that direction. And it reaches the regulation point. When the center of gravity is again crossed the perpendicular line, it rotates in that direction and reaches the other restriction point. Retained.

  As described above, the present invention separately sets and regulates the swing range of the swing interlocking member on the solenoid side serving as the drive source and the open / close range of the blade piece that is opened and closed by the solenoid. The swing range of the swing interlocking member is set to be smaller than the opening / closing range of the blade tip, and the swing interlocking motion of the swing interlocking member is stopped immediately before the blade tip reaches both the open position and the closed position. When the rotation is stopped, the solenoid driving force does not act directly on the wing piece.This reduces the impact force when the wing piece is stopped. A large load does not act on the connecting pin that receives the driving force of the solenoid, and thus the strength of the connecting pin can be lowered. For this reason, according to the present invention, instead of using a metal shaft material having excellent strength for the connecting pin, it is possible to use an interlocking pin made of a synthetic resin of the same quality as the blade piece. As a result, the interlocking pin and the blade piece are the same. Depending on the material, it is possible to form a single piece, so that the manufacturability is improved and it can be manufactured at a low cost.

Next, the present invention will be described in detail according to the illustrated embodiment, and the features thereof will be clarified.
1 is a front view of an electric tulip according to the present invention in which a blade piece is in a closed position, FIG. 2 is a plan view in the closed position, FIG. 3 is a right side view in the closed position, and FIG. 2 is a longitudinal right side view taken along line AA in FIG. 2, FIG. 5 is a longitudinal right side view taken along line BB in FIG. 2, and FIG. 6 is a longitudinal front view similarly taken along line CC. 7 is an exploded perspective view seen from the front side, and FIG. 8 is an exploded perspective view seen from the back side.

  In the drawings, reference numeral 1 denotes a mounting board for an electric tulip according to the present invention, and reference numeral 2 denotes an enclosing frame having a pocket shape provided on the front surface of the mounting board so as to surround a winning opening 3 established at the center of the mounting board 1. 4a and 4b are left and right wing pieces pivotably mounted on a pair of support shafts 5 and 5 that are passed in parallel in the front-rear direction from both sides of the winning opening 3 toward the surrounding frame 2; Reference numeral 6 denotes an entry guide port formed in a gate shape so as to protrude from the front surface of the mounting substrate 1 so as to be positioned immediately above the left and right wing pieces 4a and 4b.

  The mounting board 1 is provided to fix the electric tulip of the present invention to the game board, and at the same time serves as a board for assembling the electric tulip, and is screwed to the game board (not shown) at the left and right side edges. Holes 7 and 7 are opened.

The surrounding frame 2 is constituted by a bottom plate 8 and a decorative plate 9 rising from the front edge of the bottom plate, and has a space in which a ball can be sufficiently received. 8 is fixed to the front surface of the substrate 1.
When the frame 2 is fixed, the shaft holes 11 and 11 provided in the wing pieces 4a and 4b are passed through the support shafts 5 and 5 that are installed horizontally from the back to the rear side of the decorative plate 9, and this is rotated. The blades 4a and 4b are attached to the inside of the surrounding frame 2 by assembling freely and then inserting the rear ends of the support shafts 5 and 5 into the holes 12 and 12 provided in the mounting substrate 1. .

  The left and right wing pieces 4a and 4b are opposed to each other so as to sandwich the winning opening 3 with an interval of about one pachinko ball, and in a closed position, the inner surfaces 13a and 13b formed in a planar shape are vertically erected, A space formed by both inner surfaces faces directly below the entry guide 6, and only a ball that enters through the introduction opening 6 is received between the blades and sent to the winning opening 3.

  When the blades 4a and 4b are in the closed position, the lower wings 14a and 14b on the inner surfaces 13a and 13b side projecting downward from the support shafts 5 and 5 are provided on the bottom plate 8 of the surrounding frame 2. Abutting against the stopper 15 and the rotation in this direction is restricted. On the other hand, both the blade pieces 4a and 4b are lifted from the closed position with the support shafts 5 and 5 as fulcrums as shown in FIGS. When tilted in the left-right direction and turned to the open posture, the stepped portions 17a, 17b formed on the lower end portions on the outer surfaces 16a, 16b side of both wing pieces are brought into contact with the stoppers 18, 18 provided on the left and right edges of the bottom plate 8. And the rotation is restricted.

The left and right wing pieces 4a and 4b turned to the open posture are held in a state in which the inner surfaces 13a and 13b are inclined inward, and as a result, outside of the hit ball that enters through the injecting guide port 6, A ball that falls on the inner surfaces 13a and 13b through the outer side is received and can be used as a winning ball, which greatly reduces the hit of the hit ball.
The sphere that has entered between the blades is guided to the winning opening 3 through a guide portion 19 having an arcuate guide plate formed in the center portion of the bottom plate 8, and further extends from the back surface of the mounting substrate 1. It will be led to the safe ball gathering room formed behind the game board (not shown) through the cage 20.

In the figure, reference numeral 21 denotes a solenoid for driving the wing pieces 4a and 4b to open and close. 22a and 22b change the linear expansion / contraction movement of the plunger 23 of the solenoid 21 into a swinging motion, and the wing pieces 4a and 4b are supported on the spindles. It is a rocking interlocking member that changes to a pivoting motion with 5 and 5 as fulcrums.
The solenoid 21 is fitted on a mounting plate 24 formed by bending a metal plate into a U-shape, and is fixed to the mounting plate by a screw 25 passed from below, and the tip of the plunger 23 protrudes between the left and right plate portions 24a and 24b. It is like that.

The mounting plate 24 has a columnar shape in which mounting pieces 25a and 25b extend at right angles from left and right end edges of the left and right plate portions 24a and 24b, and the mounting pieces project from the back surface of the mounting substrate 1. The screws 28 and 28 are attached to the mounting substrate 1 by screwing the screws 28 and 28 through the through holes 27 and 27 which are in contact with the mounting bases 26 and 26 and are formed in the piece.
The solenoid 21 assembled to the mounting substrate 1 via the mounting plate 24 has a small hole formed in a lateral direction at the tip of the plunger 23 protruding forward, and passes through the connecting shaft 29. Are connected to the ends of one swing arm of the swing interlocking members 22a and 22b.

The rocking interlocking members 22a and 22b are formed in an L-shape, and bearing holes 30 and 30 are formed in the center portion where the rocking interlocking members 22a and 22b are refracted, and the fixed support shaft 31 is inserted into the bearing holes.
The fixed support shaft 31 is used to support the swing interlocking members 22a and 22b on the mounting plate 24 of the solenoid 21, and the bearing pieces 32 and 32 are suspended from the lower edges of the left and right plate portions 24a and 24b of the mounting plate. The bearings 30 and 30 are attached to both ends protruding from the right and left of the holes 33 and 33 through the washers 34 and 34, and the rocking interlocking members 22a and 22b are assembled.

The swing interlocking members 22a and 22b have holes 35 and 35 for bearing the connecting shaft 29 at the end of one swing arm that stands up, and a push-up portion at the end of the other swing arm that protrudes horizontally. And a connecting piece 36 provided with a piece 36a to be a pressing portion and a piece 36b to be a pressing portion.
The connecting piece 36 is opened forward and receives the interlocking pins 37a and 37b protruding from the back surfaces of the wing pieces 4a and 4b.

As described above, the mounting plate 24 in the first period is assembled with the solenoid 21 at the same time as the swing interlocking members 22a and 22b, so that the positional relationship between the two is kept constant and integrated.
In actual assembly, the solenoid 21 is first assembled, fixed with the screw 25, and then the plunger 23 with the connecting shaft 29 assembled in the insertion hole 38 directed in the front-rear direction is inserted and assembled. At this time, the plunger 23 is wound with a biasing coil spring 39 that compresses and repels when attracted by excitation. Next, the fixed support shaft 31 is passed through the holes 33, 33 formed in the bearing pieces 32, 32 of the mounting plate 24, and this is supported.

After this, the left and right swing interlocking members 22a and 22b are faced from both sides of the fixed support shaft 31, and the shaft ends of the fixed support shaft 31 are inserted into the bearing holes 30 and 30 and supported. The shaft end of the connecting shaft 29 is similarly inserted into the holes 35, 35 of the swing arm, and the swing interlocking members 22a, 22b and the solenoid 21 are connected.
With the above assembly, the solenoid 21 and the two rocking interlocking members 22a and 22b are assembled together through the mounting plate 24. In this state, the left and right wing pieces 42, 42 are assembled to the mounting substrate 1.

  By the way, the interlocking pins 37a and 37b are formed by integrally forming the blade pieces 4a and 4b with the same material when the synthetic resin is formed of a synthetic resin material. 1 projecting to the back side through the isolated through holes 40, 40 opened in 1 and facing the connecting pieces 36 of the swing interlocking members 22a, 22b projecting horizontally toward the front, between the upper and lower pieces 36a, 36b. It will be inserted into and connected.

FIGS. 1 to 6 show the completed state of the electric tulip of the present invention assembled as described above. Here, the left and right wing pieces 4a and 4b are erected to make it difficult for a winning ball to enter. Is shown.
In this state, the solenoid 21 is in a demagnetized state, and the plunger 23 extends from the insertion hole 38 due to the extension of the spring 39, pushes one rising swing arm forward, and swings the other swing with the fixed support shaft 31 as a fulcrum. The moving arm is pushed down and the connecting piece 36 is directed downward.
At this time, the one swinging arm of each swing interlocking member 22a, 22b comes into contact with the back surface of each of the mounting pieces 25a, 25b of the mounting plate 24, and this prevents the swinging forward by this. It is done.

When the connecting piece 36 faces downward, both the interlocking pins 37a and 37b are pushed down by the pushing pieces 36a and 36a, and are located on the lower end side of the isolated through holes 40 and 40, so that the support shaft The left and right wing pieces 4a and 4b that rotate about the fulcrum 5 and 5 are held in an upright closed position. Of course, in this case, it is needless to say that the interlocking pins 37a and 37b are desirably provided with a gap between them so as not to come into contact with the lower edge of the through holes 40 and 40.
6 and 9 show a closed posture in which the wing pieces 4a and 4b stand up. Both wing pieces have the stepped portions 14a and 14b at the lower ends of the inner surfaces 13a and 13a abutted against the stopper 15 of the surrounding frame 2. FIG. You will keep your posture.

In this state, the blade pieces 4a and 4b are placed on the inner sides of the support shafts 5 and 5 serving as pivot points and the stepped portions 14a and 14b are brought into contact with the stoppers 15 by their own weights so as to keep their postures independently. (See FIG. 9). As shown in FIGS. 5 and 10, the interlocking pins 37a and 37b and the connecting piece pieces 36a and 36a which are pressed down are provided with a gap 41 so as not to come into contact with each other.
The above-described gap 41 includes a restriction position where the swinging arms of the swing interlocking members 22a and 22b abut against the mounting pieces 25a and 25b of the mounting plate when the plunger 23 of the solenoid 21 is extended, and the step portions of the blade pieces 4a and 4b. 14a and 14b are formed by a difference from a position where the stoppers 15 and 15 are in contact with each other and the rotation is restricted. The blade 41 is converted into a closed posture by the gap 41, and each interlocking pin 37a is actually stopped. , 37 b are released from the pressing from the connecting piece 36 and released from the direct pressing by the solenoid 21.

Next, when the solenoid 21 is excited in response to the release signal in this state and the plunger 23 is pulled, the swing interlocking members 22a and 22b swing around the fixed support shaft 31 and protrude forward. , And the connecting piece 36 at the tip pushes the interlocking pins 37a and 37b positioned on the lower end side of the through holes 40 and 40 toward the upper end side.
Accordingly, with the excitation of the solenoid, the wing pieces 4a and 4b rotate with the support shafts 5 and 5 as fulcrums and the upper ends thereof outward, and the step portions 17a and 17b abut against the stoppers 18 and 18, respectively. Will stop.

11 to 18 show a state in which the blades 4a and 4b are rotated outward as the solenoid 21 is excited and the connecting piece 36 of the swing interlocking members 22a and 22b is flipped up, that is, converted into an open posture. Shows the state.
When the plunger 21 is converted into an open posture by the excitation of the solenoid 21, the rear end of the plunger 23 abuts on the rear wall 38a of the insertion hole 38 and stops, and the swing interlocking members 22a and 22b swing by this stop. Stopping and pushing-up of the interlocking pins 37a and 37b by the piece 36b of the connecting piece 36 are stopped. That is, the swing interlocking members 22a and 22b stop swinging in the opening direction using the rear wall 38a that prevents the plunger 23 from retracting when the blade pieces 4a and 4b are opened.

  On the other hand, the blade pieces 4a and 4b opened by the excitation of the solenoid 21 are rotated outward by pushing up the interlocking pins 37a and 37b, and the step portions 17a and 17b are brought into contact with the stoppers 18 and 18, respectively. At this time, the center of gravity g of each blade piece 4a, 4b passes directly above the support shafts 5, 5 and moves to the outside. The winglet will automatically turn to the open position when it exceeds just above. Of course, in this embodiment, since the interlocking pins 37a and 37b are continuously pushed up by the connecting piece 36 even after the center of gravity position g is moved outward, the swing interlocking member is forced to rotate until it stops regulating. It will be.

15 and 18 show the relationship between the connecting piece 36 and the interlocking pin 37a of the wing piece 4a in the open posture (the same applies to the interlocking pin 37b of the right wing piece 4b). A gap 42 is provided between the push-up piece 36b and the interlocking pin 37a as in the case of the closed posture.
This gap 42 is based on the difference between the stop position when the swing interlocking member 22a is released, that is, the retract stop position of the plunger 23 and the position where the stepped portion 17a of the blade piece 4a abuts against the stopper 18 and stops rotating. The wing piece 4a is released from the opening operation by the solenoid 21 at the time of stopping due to the air gap, and stops alone.

Although the electric tulip according to the present invention is not shown in the drawing, the attachment to the game board is inserted from the front side into the through-hole, and the attachment board 1 is fixed to the hole 7 with a screw when it contacts the front side of the board. .
This electric tulip is usually placed in a state in which the solenoid 21 is demagnetized in the same manner as that generally used. The plunger 23 is extended by the action of the spring 39, the connecting piece 36 of the swing interlocking members 22a and 22b is lowered, and the blade pieces 4a and 4b are erected to maintain the closed position. For this reason, only the ball that has entered the entry guide port 6 enters the winning port 3 through the wing pieces 4a and 4b.

  In the above state, when the solenoid 21 is excited by the presence of a winning ball at the winning opening 3 or by receiving a release instruction signal from the outside, the plunger 23 is drawn into the insertion hole 38. The connecting pieces 36, 36 of the swing interlocking members 22a, 22b are pushed up. For this reason, the interlocking pins 37a and 37b lowered at the time of closing are jumped up, and the wing pieces 4a and 4b on the front surface of the mounting substrate 1 are rotated outward to be converted into an open posture.

  The open posture of the wing pieces 4a and 4b is that the hitting ball can easily enter as shown in the figure. Next, when a closing instruction signal is output to the solenoid in this state, the spring 39 is demagnetized and compressed. The plunger 23 is extended by the urging, and the connecting pieces 36 and 36 are lowered as the swing interlocking members 22a and 22b swing, and the interlocking pins 37a and 37b are pushed down to convert the blade pieces into a closed posture. It will be.

  In this series of opening and closing operations, as described above, the electric tulip of the present invention is converted to the closed position, that is, to the closed posture on the drive unit side on the solenoid 21 side including the swing interlocking members 22a and 22b. Thus, one swinging arm of the swing interlocking members 22a and 22b is brought into contact with the mounting pieces 25a and 25b of the mounting plate 24, and the swinging motion is stopped using this as a stopper. In converting the piece into the open posture, the rear end of the plunger 23 is brought into contact with the rear wall 38a of the insertion hole 38, and this is used as a stopper to stop the swing interlocking member from swinging. The rocking interlocking members 22a and 22b independently regulate the rocking range.

  On the other hand, when the blades 4a and 4b are closed, the stepped portions 14a and 14b are brought into contact with the stoppers 15 and 15, respectively, to maintain the closed posture, while when released, the other stepped portions 17a and 17b are respectively connected to the stoppers 18 and 18. In this way, the wing pieces independently control the rotation range while maintaining the open posture.

  In other words, in the present invention, when the blade pieces 4a and 4b are opened and closed, the operation (swinging) range of the swing interlocking members 22a and 22b by the solenoid 21 and the operation (turning) range of the blade side are restricted. And the operation range of the swing interlocking member is set to be smaller than the operation range of the blade piece so that the swing interlocking members 22a and 22b are stopped and then the operation of the blade member is stopped. When the suspension is stopped, gaps 41 and 42 are formed between the pushing piece 36a and the pushing piece 36b of the connecting piece 36 and the interlocking pins 37a and 37b, respectively, and the blade pieces 4a and 4b are formed by the gap. The forced pressing by the solenoid 21 can be avoided when stopping.

Therefore, the electric tulip of the present invention does not receive a strong impact by the solenoid 21 when the wing piece is opened and closed. For this reason, the interlocking pins 37a and 37b for transmitting the power of the solenoid 21 to the wing piece are required to be high in the conventional electric tulip. Since it is no longer necessary to have strength, it is possible to use the interlocking pin which is integrally molded using a synthetic resin of the same quality as the blade piece.
Therefore, the electric tulip of the present invention can be easily formed into a wing piece, and can be integrally formed, so that high accuracy can be obtained at the time of molding. Therefore, an electric tulip excellent in manufacturability is provided at a low price. It can be done.

In the illustrated embodiment, as a control method on the drive unit side, the swinging arms of the swing interlocking members 22a and 22b are brought into contact with the mounting pieces 25a and 25b when closed, and the rear end of the plunger is brought into contact with the rear wall 38a when opened. Although it is assumed that the two ends of the plunger 23 are brought into contact with each other, it can be controlled by making contact with a stopper provided individually, or by stopping the swinging of the swinging arm standing up and down. These methods can be freely selected for implementation.
For example, in the latter case, the swinging arm is brought into contact with the mounting pieces 25a and 25b when closed, and the connecting shaft 29 for connecting the swinging arm to the plunger 23 is connected to the plate portions 24a and 24a of the mounting plate 24 when opened. The stop position is regulated by abutting against the rear end portions of the cut holes 43 and 43 formed in 24b, and the swing range can be determined.

On the other hand, the wing pieces 4a and 4b may be regulated by abutment between the interlocking pins 37a and 37b and the upper and lower ends of the isolated through holes 40 and 40 through which the pins pass. In short, the shape of the blade piece is not limited to one as long as it is controlled between the mounting substrate 1 and the stopper means provided between the mounting substrate 1 and the surrounding frame 9.
Since the blade pieces 4a and 4b are kept open and closed by their own weight by using the movement of the center of gravity position g, the blade pieces 4a and 4b smoothly move to the respective postures after passing the intermediate point above the support shaft 5. Will reach.
