Description

  The present invention relates to a launch control handle mechanism of a ball game machine.

  The ball game machine (so-called pachinko machine) has a game board on the front side (that is, the side facing the player), and the game board has a prize opening serving as a passage for the ball (hereinafter also referred to as game ball). A game part such as a nail, a windmill, and a symbol display device for displaying a game symbol is provided. On the lower right side of the game board, there is provided an operation handle for controlling the operation of sending out the ball onto the game board. The operation handle is provided with an operation portion that rotates within a predetermined angle range, and the operation portion is disposed at an initial position in a state in which a biasing force is applied in a counterclockwise direction by a spring or the like.

  The operation unit is an operation switch for driving the bullet launcher, and the bullet launcher is operated by rotating the operation unit clockwise from the initial position. The bullet launcher includes a ball launching mechanism that drives a hitting ball that strikes the bullet in response to a twisting operation of the operation unit. The driving of the hitting ball is performed by an electric motor or the like, and the hitting force is adjusted according to the amount of twisting operation of the operating portion. That is, when the player holds the operation handle and twists the operation unit in the clockwise direction, a drive signal is supplied to the bullet launching device and the ball launching mechanism is driven. The ball is hit with a hitting force according to the amount of operation. The hit ball is sent to the upper part of the game board through a rail communicating with the ball launcher.

  The bullet ball fed onto the game board rolls and falls while repeatedly colliding and repelling with game parts such as nails. When the game ball passes through the winning opening in the middle of the fall, a predetermined number of bullets are paid out to the player as a prize ball. In addition, a gaming machine equipped with a symbol display device performs a lottery when a game ball passes a winning opening, and a game symbol corresponding to the lottery result is displayed on the symbol display device. Yes.

  Since the operation handle including the operation unit is fixed to the gaming machine, in order for the player to hold the operation handle and operate the operation unit, it is necessary to place the operating hand (usually the right hand) in a certain range of positions. was there. That is, the player must maintain a certain posture in order to control the operation unit. As a result, there is a problem that the player may get tired by maintaining the posture and may not be able to concentrate and enjoy the game.

  Therefore, in order to allow the player to operate the gaming machine in a relaxed posture, the operation handle is placed on the front side of the player (in the direction from the gaming machine body to the player) or vice versa (from the player to the game). A technique that can be adjusted and arranged in a direction toward the machine main body has been proposed (Patent Document 1).

  The launch control handle mechanism in Patent Document 1 includes a handle unit including an operation unit, a handle base and a cap for rotatably holding the operation unit, a handle holder for disposing the handle unit on the front side of the gaming machine, have. Such a handle holder includes an outer cylinder fixed to the gaming machine, an inner cylinder inserted into the outer cylinder and capable of sliding in the outer cylinder, and a fixing screw for fixing the inner cylinder to the outer cylinder. And. The inner cylinder supports the handle holder. In addition, the shaft portion of the fixing screw is inserted into a mounting hole provided in the outer cylinder, and when the tip of the shaft portion of the fixing screw is advanced toward the inside of the outer tube (that is, when tightened), The screw shaft portion comes into contact with and presses the inner cylinder. That is, the inner cylinder is fixed to the outer cylinder by the pressing force of the fixing screw.

  According to the launch control handle mechanism having such a configuration, after the inner cylinder is slid with respect to the outer cylinder and the handle unit is arranged at a desired position, the fixing screw is tightened to fix the inner cylinder to the outer cylinder. it can. Thus, the player can arrange the handle unit in accordance with the player's own posture and the like.

Further, in Patent Document 1, a plurality of engagement holes that can engage the shaft portion of the fixing screw with the cylindrical surface of the inner cylinder are provided in a row at predetermined intervals in the sliding direction, and the engagement holes are tightened when the fixing screw is tightened. Also disclosed is a technique for fixing the inner cylinder to the outer cylinder by inserting the screw shaft portion into the outer cylinder.
Japanese Patent Laid-Open No. 2002-360802

  However, according to the technique in which the fixing screw is brought into contact with the inner cylinder and fixed as described above, when a force exceeding the frictional force at the portion where the screw and the inner cylinder are in contact is applied in the sliding direction of the inner cylinder. The inner cylinder can move along the same direction. Therefore, the inner cylinder cannot be completely fixed to the outer cylinder.

  Moreover, it is possible to prevent the inner cylinder from sliding relative to the outer cylinder by providing the engagement hole and inserting the shaft portion of the fixing screw into the engagement hole. However, although it is necessary to align the center of the engaging hole and the center axis of the shaft portion of the fixing screw in order to insert the fixing screw into the engaging hole, the position of the engaging hole is visually recognized from the outside. There is a problem that it is difficult for reasons such as being unable to do so.

  Furthermore, when the handle unit is brought closer to the player's side, that is, when the inner cylinder is pulled out from the outer cylinder, the engagement hole provided on the cylindrical surface of the inner cylinder is exposed to the outside. There is a risk that foreign objects such as piano wires may be inserted into the gaming machine through the exposed engagement holes. There is a problem that the insertion of such a foreign object may cause an illegal act (so-called goto action) such as an act of contacting the control circuit board of the gaming machine.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem as an example, and it is an object of the present invention to provide a firing control handle mechanism in which an operation handle can be arranged at a desired position.

(Not shown) is arranged. Further, around the symbol variable display device, a nail, a windmill, a start winning opening, a normal winning opening, an attacker, an out opening, etc. (all not shown) are provided. Each winning opening (not shown) is provided with a winning ball detection sensor (not shown) for detecting that a game ball has passed through each winning opening.

  A lower door frame 5 is provided below the front frame 4. The lower door frame 5 is provided with a supply tray 5a for supplying a game ball and an operation handle 6a of a launch control handle mechanism 6 for controlling the launch of the game ball and controlling the launch intensity. The operation handle 6a is provided with an operation unit 7 that rotates within a predetermined angle range. When a player, that is, an operator of the gaming machine 1 inserts a gaming ball into the supply tray 5a, the gaming ball is placed on the back side of the gaming machine 1 via a guide path (not shown) provided in the supply tray 5a. Is guided to a bullet ball launcher (not shown). The operator rotates the operation unit 7 of the operation handle 6a by a predetermined amount to drive the bullet launcher. The bullet launcher launches a game ball toward the upper side of the game area 3 a of the game board 3. The launched game ball passes through the winning opening on the way from the upper side of the game area 3a or is collected from the out opening.

  In addition, the control which performs control for operating various apparatuses, such as sound generators (not shown), such as a symbol variable display apparatus (not shown) and a speaker (not shown), on the back side of the gaming machine 1 is performed. A circuit device (not shown), a ball dispensing device (not shown), and the like are assembled.

  As shown in FIG. 2, the operation handle 6 a of the firing control handle mechanism 6 includes an operation unit 7, a handle base 8, and a face cover 9, and the handle base 8 and the face cover 9 rotate the operation unit 7. It is fixed in a state of being sandwiched freely. The handle base 8 is made of a cylindrical body with a bottom, and receives a rotation transmission unit (not shown) that transmits the rotation of the operation unit 7 to a bullet launcher (not shown). The rotation transmitting unit includes a launching strength adjusting volume (not shown), an adjusting gear (not shown), and the like. The impact strength adjusting volume includes a plate-like base (not shown) and a cylindrical shaft portion (not shown) that is rotatably provided on the base. The base is fixed to the handle base 8. Further, the cylindrical shaft portion is interlocked with the operation portion 7 via the adjustment gear, and is rotated according to the rotation amount of the operation portion 7. The impact strength adjusting volume is electrically connected to a control circuit device (not shown), and supplies a rotation amount signal corresponding to the rotation amount of the cylindrical shaft portion to the control circuit device. It has become. Based on the rotation amount signal, the control circuit device supplies a drive signal corresponding to the rotation amount of the operation unit 7 to the bullet launching device. Upon receiving the drive signal, the bullet launcher drives a hitting ball (not shown) of a ball launching mechanism (not shown) that strikes the game ball in response to the twisting operation of the operation unit 7, and responds to the drive signal. The game ball is launched on the surface of the game board with the launch strength (according to the rotation amount of the operation unit 7). As described above, the operation unit 7 commands the bullet launching device according to the rotation amount of the bullet launching strength.

  One end of a torsion spring (not shown) is attached to the handle base 8. On the other hand, the other end of the torsion spring is fixed to the operation unit 7, and the central part of the torsion spring wound in a coil shape is the center of rotation of the operation unit 7 when the operation unit 7 is rotated. It is inserted into a central protrusion (not shown). Due to such a torsion spring, the operation portion 7 is arranged at the reference position in a state where a biasing force is applied in the counterclockwise direction. The rotation position of the cylindrical shaft portion of the impact strength adjusting volume at the reference position is the reference rotation position (rotation amount = 0).

  One end of a substantially cylindrical inner cylinder portion 10 (longitudinal rod-like body) is attached to the outer side surface of the bottom surface of the handle base 8. That is, the operation handle 6 a is supported at the distal end portion of the inner cylinder portion 10. The inner cylinder portion 10 and the handle base 8 may be formed integrally.

  The inner cylinder part 10 is inserted in a substantially cylindrical outer cylinder part 11 fixed to the gaming machine 1 and slides in the outer cylinder part 11. A groove portion 10 a extending in the longitudinal direction is formed on the cylindrical surface of the inner cylinder portion 10, and the groove portion 10 a protrudes toward the inside of the opening 11 a of the outer cylinder portion 11. 11b. By the groove portion 10a and the protrusion portion 11b, the inner cylinder portion 10 is guided in the longitudinal direction while the rotation around the longitudinal central axis is controlled.

  The outer cylinder part 11 is provided with a positioning mechanism 12 that positions and fixes the inner cylinder part 10 with respect to the outer cylinder part 11, and an operation knob 13 that constitutes the positioning mechanism 12 and operates the mechanism is provided. It protrudes toward the outside of the outer cylinder part 11 and is provided. The operation knob 13 is inserted so as to be slidable with respect to the through hole 14 that penetrates the cylindrical surface of the outer cylinder portion 11. The positioning mechanism 12 will be described in detail later.

  As shown in FIG. 3, the inner cylinder part 10 has a predetermined length in the longitudinal direction of the inner cylinder part 10 in the vicinity of the other end part opposite to one end part (tip part) to which the handle base 8 is attached. Are provided with a plurality of ridges 15 juxtaposed with each other at regular intervals. Each protrusion 15 protrudes outward from the cylindrical surface of the inner cylinder portion 10, and extends along the substantially circumferential direction on the cylindrical surface of the inner cylinder portion 10. Here, the protrusion 15 includes an endless brim that continuously surrounds the inner cylinder portion 10. The range of the region where the ridge group is provided corresponds to the range in which the inner cylinder portion 10 slides. In addition, in the inner cylinder part 10, the position near the other end on the side opposite to the one end (tip) to which the handle base 8 is attached is the position where the protrusion group is provided. At a position on the opposite side in the circumferential direction of the cylindrical portion 10, a stopper 10 b is provided to prevent the inner cylindrical portion 10 from coming out of the outer cylindrical portion 11 and to define a sliding range of the inner cylindrical portion 10. It has been. The operation of the stopper 10b will be described later.

  As shown in FIGS. 4 and 5, between any two ridges 15 of the ridges 15, the engagement pieces 16 that can engage with the two ridges 15 are the inner cylinder part 10 and the outer cylinder part 11. Between the two. For example, as shown in FIG. 4, the engagement piece 16 has a size corresponding to the height and interval of the protrusions 15 so as to fit between adjacent protrusions 15, and the protrusions 15 extend. It consists of a longitudinal piece arranged in parallel with the direction in which it runs. The engagement piece 16 is attached to the positioning mechanism 12 and is coupled to the operation knob 13 constituting the positioning mechanism 12 at an intermediate position in the longitudinal direction of the outer cylinder portion 11. Note that the operation knob 13 is allowed to move in a direction substantially perpendicular to the cylindrical surface of the outer cylindrical portion 11, and is limited to the direction in which the inner cylindrical portion 10 slides. When the operation knob 13 is pulled toward the outer side of the outer cylinder part 11, the engaging piece 16 moves from the inner cylinder part 10 side toward the outer cylinder part 11 side in accordance with this, and the operation knob 13 is moved to the outer cylinder part 11 side. When pushed inward, the engagement piece 16 moves from the outer tube portion 11 side toward the inner tube portion 10 side accordingly. The stroke of the operation knob 13, that is, the moving distance of the engagement piece 16 is set to be larger than the height of the protrusion 15.

  One end of a spring portion 17 is attached to each end of the engagement piece 16 in the longitudinal direction (circumferential direction of the inner tube portion), and the other end of each spring portion 17 is attached to the inside of the outer tube portion 11. ing. The spring portion 17 constitutes the positioning mechanism 12, and the spring portion 17 is attached so as to urge the engaging piece 16 toward the inner cylinder portion 10 side. Therefore, when the operation knob 13 is not operated, the engagement piece 16 presses the inner cylinder portion 10 by the spring portion 17. In a state where the engagement piece 17 presses the inner cylinder portion 10, the engagement piece 16 is disposed between any two of the protrusions 15 (for example, between adjacent ones). Then, the engagement piece 16 and the protrusion 15 are engaged. Since the engagement piece 16 is restricted in movement in the sliding direction of the inner cylinder part 10, the inner cylinder part 10 is fixed to the outer cylinder part 11.

  Note that the opening 11c on the gaming machine side of the outer cylinder portion 11 is provided with the other end portion on the opposite side to the one end portion (tip portion) to which the handle base 8 of the inner cylinder portion 10 is attached and a stopper. A stopper 11d that can come into contact with 10b is provided. The stopper 11d prescribes | regulates the range which the inner cylinder part 10 goes to the game machine side among the sliding ranges of the inner cylinder part 10. FIG. In addition, a stopper 11e that protrudes inside the outer cylinder portion 11 and can contact the stopper 10b is provided in the vicinity of the center portion of the outer cylinder portion 11 in the longitudinal direction. The stopper 11e prescribes | regulates the range which the inner cylinder part 10 goes to an operator side among the sliding ranges of the inner cylinder part 10. FIG. As described above, the inner cylinder portion 10 is prevented from coming out of the outer cylinder portion 11 by the stoppers 10b, 11d, and 11e.

  Next, positioning of the operation handle 6a using the positioning mechanism 12 will be described. For example, as shown in FIG. 4, in a state where the inner cylinder portion 10 is pushed most into the gaming machine side, the engagement piece 16 is a ridge 15 disposed on the operation handle side among the plurality of ridges 15 and It is engaged with the ridge 15 adjacent to this. The operation handle 6 a is positioned by pulling the operation knob 13 toward the outside of the outer cylinder portion 11 against the urging force of the spring portion 17. By pulling the operation knob 13 toward the outside of the outer cylinder portion 11, the engagement piece 16 moves from between the two protrusions 15 toward the outer cylinder portion 11, and the engagement piece 16 and the protrusion 15 Is disengaged (FIG. 6). When the engaged state is released, the inner cylinder portion 10 becomes slidable, and the operator can move the operation handle 6a to a desired position. When the operation handle 6a is disposed at an arbitrary position (for example, the position where the inner cylinder portion is most pulled out toward the operator as shown in FIG. 7), when the operation of pulling the operation knob 13 outward is stopped, the spring portion The engagement piece 16 is arranged between the protrusions 15 in a combination different from the above-described two protrusions 15 by the urging force of 17 (FIG. 7). As a result, the sliding of the inner cylinder part 10 is limited, and the operation handle 6a can be arranged at the arbitrary position.

  As described above, the positioning mechanism 12 positions the engagement piece 16 in the longitudinal direction of the inner cylinder portion. As a result, the operator operates the positioning mechanism 12 including the operation knob 13 and the spring portion 17 so that the protrusion 15 and the engagement piece 16 are engaged with each other or the engagement is released. The engagement piece 16 can be positioned with respect to the protrusion 15 provided on the inner cylinder portion 10 by selection. In other words, the operator can place the operation handle 6a at a desired position in accordance with the physique and the like. As a result, even if the operator operates the gaming machine for a long time, the operator is less likely to feel fatigue, and the operability such as ease of operation of the operation unit 7 can be improved.

  In addition, since the movement of the inner cylinder portion 10 is limited by the engagement between the protrusion 15 and the engagement piece 16, the operation handle 6a can be moved even if a force is applied in the sliding direction of the operation handle 6a. It is difficult to move in the sliding direction. Therefore, the operation handle 6a can be securely fixed.

  As shown in FIG. 8, when the operation knob 13 is finished, the operation handle 6a is not completely fixed when the engagement piece 16 is on the top of the protrusion 15, so the operation handle 6a is When viewed from the operator, it can be moved to the front side (operator side) or the back side (game machine side). However, when the operation handle 6a is slightly moved toward the front side or the back side, the engagement piece 16 is disposed between the front side or the back side ridges 15 by the urging force of the spring portion 17. That is, when the operator arranges the operation handle 6a at an arbitrary position and finishes the operation of the positioning mechanism 12, even if the engagement piece 16 does not fit between the protrusions 15, the operation handle 6a is moved to the near side. Alternatively, they can be reliably engaged by slightly moving to the back side.

  As described above, since the positioning mechanism 12 is not configured to be able to fix the operation handle 6a only when the engagement piece 16 is reliably positioned between the protrusions 15, the operator determines the position of the operation handle 6a. Even if it is arbitrarily selected and the operation of the positioning mechanism 12 is finished, the operation handle 6a can be securely fixed at or near the selected position. That is, the operation of positioning the operation handle 6a by the positioning mechanism 12 can be performed reliably in a short time.

For example, as shown in FIG. 8, the top surface of the protrusion 15 is formed into a convex curved surface so that the engagement piece 16 and the protrusion 15 can be engaged in a shorter time. Is preferred. In addition, although not shown, a surface on the side opposite to the operation knob 13 side of the engaging surface where the engaging piece 16 engages the protrusion 15 may be a convex curved surface. Furthermore, both the top surface of the ridge 15 and the surface of the engagement piece 16 on the side opposite to the operation knob 13 may be formed of a convex curved surface. Moreover, all or a part of the outer cylinder part 11 may be made of a transparent material, and the protrusion 15 may be visible from the outside. For example, as shown in FIG. 8, a window portion 11 f made of a transparent material may be provided in the outer cylinder portion 11 in the vicinity of the positioning mechanism 12.
(Example 2)
The positioning mechanism 12 is not limited to the configuration as in the first embodiment. For example, as shown in FIG. 9, the positioning mechanism 12 can use a lever mechanism.

  That is, the engagement piece 16 and the operation knob 13 are coupled via the lever 18, and the engagement piece 16 and the operation knob 13 are arranged with the fulcrum 19 of the lever 18 interposed therebetween. The lever 18 and the engagement piece 16 and the lever 18 and the operation knob 13 are both coupled to be freely rotatable. The fulcrum 19 of the insulator 18 is provided closer to the engagement piece 16. In addition, one end of the spring portion 17 is attached in the vicinity of the portion where the insulator 18 and the engagement piece 16 are coupled, and the other end of the spring portion 17 is attached to the outer cylinder portion 11. The spring portion 17 is attached so as to urge the insulator 18 toward the outer cylinder portion 11, and the engagement piece 16 is urged toward the inner cylinder portion 10 by the spring portion 17. The operation knob 13 is inserted so as to be able to slide through a through hole 14 that penetrates the cylindrical surface of the outer cylinder portion 11. The rest of the configuration except for the above points is almost the same as the firing control handle mechanism 6 described above.

The positioning mechanism 12 having such a configuration presses the engagement piece 16 toward the inner cylinder portion 10 by the urging force of the spring portion 17 in a state where the operation knob portion 13 is not operated (FIG. 9A). When the operation knob 13 is pushed toward the outer cylinder portion 11, one end of the lever 18 rotates around the fulcrum 19, and the other end of the lever 18 rotates around the fulcrum 19 accordingly. The engagement piece 16 coupled to the other end by such rotational movement moves from the inner cylinder part 10 toward the outer cylinder part 11 (FIG. 9B). When the engagement piece 16 is disposed at a position higher than the height of the ridge 15 by pushing the operation knob 13, the engagement state between the ridge 15 and the engagement piece 16 is released, and the inner cylinder portion 10 becomes the outer cylinder. It becomes slidable with respect to the part 11. That is, the operator can place the operation handle 6a at an arbitrary position. After the operation handle 6 a is disposed at an arbitrary position, when the operator stops the pushing operation of the operation knob 13, the operation knob 13 is pulled out of the outer cylinder portion 11 by the spring portion 17. In response to this, one end of the insulator 18 rotates around the fulcrum 19, and the other end of the insulator 18 rotates around the fulcrum 19. The engagement piece 16 coupled to the other end by such rotational movement moves from the outer cylinder portion 11 toward the inner cylinder portion 10 and is disposed between the two protrusions 15. As a result, sliding of the inner cylinder part 10 comes to be restricted. Even with the above-described configuration, the operator can place the operation handle at an arbitrary position.
(Example 3)
The engaging piece 16 may be engaged with the protrusion 15 at at least two positions in the circumferential direction around the longitudinal central axis direction of the inner cylinder portion 11.

  For example, as shown in FIGS. 10 and 11, the firing control handle mechanism 6 includes a positioning mechanism between the inner cylinder portion 10 and the outer cylinder portion 11, and the positioning mechanism includes a U-shaped clamp portion 20 and an inner cylinder portion. It has a cylindrical shape into which the cylindrical portion 10 is inserted, and an engaging portion 21 disposed so as to be sandwiched between the clamp portions 20 in a U-shaped space. 10 and 11, the clamp portion 20 is arranged so that the U-shaped opening is opened on the right side, but is not limited thereto, and the opening can be arranged so as to open in an arbitrary direction.

  The engaging portion 21 has two surfaces (for example, upper and lower surfaces of the rectangular cylindrical body 22 as shown in FIGS. 10 and 11) that face each other through the rectangular cylindrical body 22 and the inner side of the cylinder of the rectangular cylindrical body 22. An opening 23 penetrating through a part, and a longitudinal shape disposed outside the rectangular cylinder 22 so as to cover the opening of the opening 23 and being urged away from the rectangular cylinder 22 And a leaf spring 24. The leaf spring 24 includes a longitudinal hole portion 24a opened along the longitudinal direction in the vicinity of both end portions in the longitudinal direction (circumferential direction of the inner cylinder portion 10), and is inserted into the longitudinal hole portion 24a. It is attached to the rectangular cylindrical body 22 by a stopper 25. In the longitudinal hole portion 24 a, the locking portion 25 is slid in the longitudinal direction when the leaf spring 24 that is mountain-shaped toward the outside of the rectangular cylinder 22 is elastically deformed flatly. It is installed to do. An engagement piece 16 that protrudes toward the inner cylinder portion 10 inside the rectangular cylinder 22 is provided inside the opening 23 at a substantially center in the longitudinal direction of the leaf spring 24.

  The inner cylinder portion 10 inserted through the engaging portion 21 is disposed at two positions (upper and lower cylinder surfaces of the inner cylinder portion 10) so as to sandwich the inner cylinder portion 10 and outward from the cylinder surface. A ridge 15 projecting toward the end is provided. The ridges 15 at the two positions constitute ridge groups juxtaposed with each other at a predetermined constant interval in the longitudinal direction of the inner cylinder portion 10 at each position. The protrusion 15 and the engagement piece 16 are disposed so as to face each other.

  One end portion of the U-shaped body of the clamp portion 20 has a protruding portion that is in a direction orthogonal to the extending direction of the end portion and protrudes toward the inside (from the bottom to the top) of the U-shaped opening at the end portion. 20a is provided. Further, a screw fastening portion 26 is provided at the other end portion so as to face the protruding portion 20a and linearly move toward or away from the protruding portion 20. The screw fastening portion 26 is inserted through the through hole 14 penetrating the upper portion of the cylindrical surface of the outer cylinder portion 11, and a knob 26 a for operating the screw fastening portion 26 is disposed outside the outer cylinder portion 11. The protruding portion 20a and the screw fastening portion 26 can be brought into contact with a substantially central portion (a portion elastically deformed into a mountain shape) of the leaf spring 24 of the engaging portion 20a. Other configurations are almost the same as those of the above-described embodiment.

  As shown in FIG. 10, when the U-shaped opening between the screw fastening portion 26 and the protruding portion 20 a is wide, that is, when the screw fastening portion 26 is loosened, the engagement is performed by the urging force of the leaf spring 24. The piece 16 is located away from the ridge 15. In this state, the inner cylinder part 10 is slidable with respect to the outer cylinder part 11, and the operation handle 6a can be disposed at an arbitrary position.

  Here, by screwing the screw fastening portion 26 toward the engaging portion 21, that is, by tightening the screw fastening portion 26, the interval between the U-shaped openings is narrowed so that the protruding portion 20 a and the screw fastening portion 26 contact the leaf spring 24. Further, by performing a tightening operation, a tightening force exceeding the urging force of the leaf spring 24 is applied to the leaf spring 24. At this time, the leaf spring 24 is deformed by the tightening force, and the central portion of the leaf spring 24 moves toward the inner cylinder portion 10. At this time, the leaf spring 24 slides with respect to the locking portion 21, and the engagement piece 16 advances toward the inner cylinder portion 10 and engages with the protrusion 15 (FIG. 11). In such a state, the inner cylinder part 10 is fixed to the outer cylinder part 11.

As described above, the operation handle 6a can be arranged at an arbitrary position also by the configuration in which the engagement piece 16 is engaged with the protrusion 15 at two positions. By using a plurality of engagement positions between the protrusion 15 and the engagement piece 16, the inner cylinder portion 10 can be more reliably positioned with respect to the outer cylinder portion 11. Although not shown, the projecting portion 20a may be movable in the projecting direction with respect to the clamp portion 20, and may be movable toward or away from the screw fastening portion 26, for example. The protrusion 20a may be coupled to an interlocking mechanism (not shown) that interlocks with the screw fastening portion 26. For example, the protrusion 20a is interlocked with an operation of screwing the screw fastening portion 26 toward the protrusion 20a. It is good also as 20a moving toward the screw fastening part 26. FIG.
(Example 4)
The form in which the engagement piece 16 engages with the protrusion 15 at at least two positions in the circumferential direction around the longitudinal central axis direction of the inner cylinder portion 11 is not limited to the configuration as described above. For example, it is good also as using the U-shaped leaf | plate spring arrange | positioned so that an inner cylinder part may be inserted | pinched.

  For example, as shown in FIG. 12, the inner cylinder portion 10 is disposed at two positions sandwiching the inner cylinder portion 10, that is, at positions facing each other via the inner cylinder portion 10, and protrudes outward from the cylinder surface. The protruding ridges 15 are provided above and below the cylindrical surface of the inner cylindrical portion 10. The ridges 15 at the facing positions constitute ridge groups juxtaposed with each other at a predetermined constant interval in the longitudinal direction of the inner cylinder portion 10 at each position. A U-shaped leaf spring for placing the inner cylinder part 10 in a U-shaped inner space so as to sandwich the inner cylinder part 10 between the inner cylinder part 10 and the outer cylinder part 11 in which the inner cylinder part 10 is inserted. 27 is arranged. The U-shaped leaf spring is arranged so that the U-shaped opening opens toward the right side of the inner cylinder portion 10 as shown in FIG. 12, but the opening is not limited to this, and the opening is in an arbitrary direction. Can be arranged to open.

  The inside of the U-shape of the U-shaped leaf spring 27 is normally slightly larger than the outer diameter of the inner cylinder part 10 and is opposed to each other via the inner cylinder part 10 although it is separated from the cylindrical surface of the inner cylinder part 10. It is narrower than between the top parts of the protrusion part 25 of the position to perform, and a part of U-shaped leaf | plate spring 27 is arrange | positioned between the said top parts. That is, at each of the opposed positions, each end portion of the U-shaped leaf spring 27 is disposed between two projecting ridges 15 adjacent in the longitudinal direction of the inner cylinder portion 10, and engages with them. The sliding of the inner cylinder part 10 is restrict | limited.

  An operation knob 13 that protrudes toward the outer side of the U-shape, that is, the outer cylinder portion 11, is coupled to the U-shaped bottom portion of the U-shaped leaf spring 27. An end portion of the operation knob 13 opposite to the connection portion with the U-shaped plate spring 27 protrudes outside the outer cylinder portion 11 through a through hole 14 penetrating the cylindrical surface of the outer cylinder portion 11. . The operation knob 13 is slidable through the through-hole 14 and can press the U-shaped bottom portion of the U-shaped leaf spring 27 toward the inside of the U-shape. The distal end portion of the U-shaped spring 27 is fixed by a locking portion 28 so as to be rotatable around the locking portion 28.

  As shown in FIG. 12, the launch control handle mechanism 6 having the above-described configuration is configured so that the end portions of the U-shaped leaf springs 27 are adjacent to each other in the longitudinal direction of the inner cylinder portion 10 when the operation knob 13 is not operated. It is engaged with the protruding ridge 15. That is, the U-shaped leaf spring 27 acts as an engagement piece.

  When the operation knob 13 is pushed toward the inner cylinder portion 10, as shown in FIG. 13, each end portion of the U-shaped plate spring 27 expands and deforms in the vertical direction and becomes wider than the protrusion 15 at the facing position. Disengages. That is, the engagement state between the engagement piece and the protrusion by the U-shaped plate spring 27 is released. As a result, the inner cylinder part 10 becomes slidable with respect to the outer cylinder part 11, and the operator can arrange the operation handle at an arbitrary position.

  When the operation of the operation knob 13 is finished after the position of the operation handle is determined, the U-shaped leaf spring 27 returns to the shape before the operation by the restoring force, and again engages with the protrusion 15 adjacent in the longitudinal direction. Therefore, the sliding of the inner cylinder part 10 is restricted by the U-shaped leaf spring 27 and the protrusion 15 that act as the engagement pieces, and the inner cylinder part 10 is fixed to the outer cylinder part 11.

  As described above, the operation handle can be arranged at an arbitrary position also by the configuration in which the engagement piece by the U-shaped plate spring 27 is engaged with the protrusion 15 at two positions.

  In addition, a protrusion and an engaging piece are good also as engaging in two or more positions in the circumferential direction around the longitudinal circumferential direction of an inner cylinder part.
