Description

  The present invention relates to a cylinder lock, and more particularly, to a cylinder lock that can prevent an assembly error during assembly of a main body.

  In order to regulate the opening of the front door of a gaming machine, a cylinder lock has been conventionally used.

  As a conventional long cylinder lock for gaming machines, a cord-fixed long cylinder lock has been proposed (see Patent Document 1). Here, the code indicates a key pattern of the cylinder lock (for example, an uneven pattern of the key). Therefore, since the regular key for locking or unlocking the cylinder lock whose code is fixed cannot be changed, if the key is stolen, the cylinder lock must be replaced.

  For this reason, a variable-code long cylinder lock has been proposed in which this code is variable and can be used by changing the pattern of a regular key to be locked or unlocked as required (Patent Document 2). reference). The long-cylinder lock of variable code type has a lock mechanism built in a cylindrical case, a reset mechanism built in a cylindrical base, and each is connected by a joint plate.

JP 2001-65207 A Japanese Patent Laid-Open No. 9-235921

  By the way, the above-described cylinder lock functions as a lock because the cylindrical output shaft and the cylindrical joint cam on the outer peripheral side are coaxially arranged on the inner peripheral side driven with the rotation of the key. In this case, a small pin called a joint block is inserted into a hole portion of the output shaft through a hole portion provided in a joint cam having substantially the same diameter on the side surfaces of each other and substantially the same diameter. For this reason, when the output shaft receives the torque generated with the rotation of the key, the torque is transmitted to the joint cam via the joint block, so that both rotate in the same phase. The hole is provided with a spring at the bottom, and the joint block is pressed outward with respect to the rotation shaft by the spring.

  Then, when changing the code of the cylinder lock mechanism in accordance with the key pattern, that is, when resetting, the joint block is pressed in the direction opposite to the repulsive force of the spring by the reset button so that the joint block can be By pushing into the part, the restriction to the joint cam by the joint block is released. As a result, the joint cam does not rotate even when the output shaft rotates. At this time, the cylinder lock mechanism part cancels the restriction of the joint plate and changes the pattern with the key rotated 180 °. I am letting.

  However, if the cylinder lock mechanism is connected 180 ° reversely, when the output shaft and the joint cam are assembled, the output shaft is assembled to the joint cam with the joint block being pushed inside. Despite the fact that the hole provided and the hole of the output shaft are assembled at the same position, there is no difference in appearance, so when the cylinder lock mechanism and the reset mechanism are assembled, In some cases, the joint block can be connected in the opposite direction of 180 °. When locking and unlocking, the joint block does not communicate with the hole of the joint cam, and the joint cam may not rotate even if the key is turned.

  The present invention has been made in view of such a situation, and is intended to prevent an assembly error that occurs during the assembly operation of the output shaft and the cylinder lock mechanism.

An opening / closing plate and a tumbler plate are mounted, and the key code of the key of the cylinder lock 1 (inner cylinder 14) can be reset as necessary. A spring cover 31 is mounted on the upper part of the inner peripheral cylinder 14 so that a spring for the opening / closing plate comes into contact therewith. The configuration of the inner cylinder 14 is not limited to that described above, and may be any configuration that can change the key code. Note that the detailed structure of the inner cylinder 14 may be the same as that disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-336775, and the description thereof will be omitted.

  Further, a front connecting shaft 32 is provided so as to contact the rear portion (right side in the figure) of the inner peripheral cylinder 14. The front end of the front connecting shaft 32 is formed in a circular plane shape, and convex portions 32a-1 and 32a-2 are formed on the surface thereof asymptotically with respect to a plane cross section perpendicular to the rotation axis. The front connecting shaft 32 is rotated together with the inner peripheral cylinder 14 by engaging with the recesses 14b-1 and 14b-2 (FIG. 5) provided at corresponding positions on the rear portion of the inner peripheral cylinder 14. It is configured.

  Further, a shaft hole 32b having substantially the same shape as the front end portion of the connection shaft 33 is provided at the rear end of the front connection shaft 32. By inserting the front end portion of the connection shaft 33, the inner cylinder 14 rotates. And the connecting shaft 33 is rotated.

  The connecting shaft 33 has a substantially rectangular cross section, and is provided with a concave portion 33a at the top and a curved surface portion 33b with a curved surface at the bottom so as to be asymmetric with each other. The shaft hole 32b of the 32 and the shaft hole 36a of the output shaft 36 are configured to have substantially the same shape.

  Further, a middle outer cylinder 34 is inserted into the rear part (right side in the figure) of the front outer cylinder 11. Insertion portions 34b and 34c are respectively provided along the outer periphery of the middle outer cylinder 34 at the front and rear portions of the middle outer cylinder 34, and the middle outer cylinder 34 is inserted into the front outer cylinder by the insertion portions 34b and 34c. 11 is inserted in the left and right directions in the figure, and is inserted into the relay pipe 12.

  Further, a caulking pin mounting hole 34a-1 is provided in the front portion of the middle outer peripheral cylinder 34. Although not shown in this figure, the lower outer caulking pin mounting hole in the figure is not shown in this figure. A caulking pin mounting hole 34a-2 is provided at a position facing 34a-1. The middle outer cylinder 34 is fixed to the front outer cylinder 11 by engagement pins 30-1 and 30-2. That is, each of the engagement pins 30-1 and 30-2 passes through the caulking pin mounting holes 11 a-1 and 11 a-2 of the front outer cylinder 11 and is used for mounting caulking pins provided at the front of the middle outer cylinder 34. The holes 34a-1 and 34a-2 are configured to be engaged.

  The middle outer cylinder 34 and the relay pipe 12 are fixed by caulking, and the relay pipe 12 and the rear outer cylinder 13 are fixed by caulking.

  The joint cam 39 is inserted into the rear outer cylinder 34. The output shaft 36 is inserted into the joint cam 39. The front connecting shaft 32 is inserted into the middle outer peripheral cylinder 34.

  As described above, the output shaft 36 is provided with the shaft hole 36a having substantially the same shape as the cross section of the connecting shaft 33. The connecting shaft 33 is inserted into the shaft hole 36a to be engaged, and the output shaft 36 is It is configured to rotate together with the connecting shaft 33.

  The outer shape of the output shaft 36 has a circular shape, and is configured to engage with the rear inner side of the joint cam 39. The output shaft 36 is provided with a recess that engages with the joint block 38. When the reset button 35 is not pressed, the joint block 38 is pressed in the outer peripheral direction by the repulsive force of the spring 37, so that the joint block 38 is fitted with the concave portion 39 b of the joint cam 39, and the output shaft 36 is moved by the joint block 38. Since it is connected (fixed) to the joint cam 39, it is configured to be rotated together with the joint cam 39 when the output shaft 36 is rotated. In addition, when the reset button 35 is pressed, the joint cam 38 is not engaged with the recess 39b of the joint cam 39, and the joint cam 39 is not rotated even if the output shaft 36 is rotated. It is configured.

  FIG. 3 is a longitudinal sectional view in the direction in which the key of the cylinder lock 1 is inserted.

  When a regular key is inserted into the cylinder lock 1 from the key hole 14a and rotated, the inner peripheral cylinder 14 is rotated. Further, as the inner peripheral cylinder 14 rotates, the front connecting shaft 32 whose convex portion 32a is engaged with the inner peripheral cylinder 14 is also rotated. Further, as the front connecting shaft 32 rotates, the connecting shaft 33 inserted and engaged in the shaft hole 32b is also rotated. Further, since the connecting shaft 33 is inserted into and engaged with the shaft hole 36a of the output shaft 36, the output shaft 36 is also rotated, and the joint cam 39 connected to the output shaft 36 by the joint block 38 is also rotated. Moved.

  Thus, by rotating the key inserted from the left keyhole 14a in the drawing, the joint cam 39 is rotated, and the cylinder lock 1 is unlocked or locked.

  The relay pipe 12 is cylindrical, and the connecting shaft 33 has a constant cross-sectional shape that is perpendicular to the rotation axis of the inner peripheral cylinder 14. Accordingly, the relay pipe 12 and the connecting shaft 33 are manufactured in the longest possible state, and can be set to various depths by being cut and used at an arbitrary length when assembled. Is possible. For this reason, in the cylinder lock 1, even when the length in the depth direction is changed and assembled, the joint cam 39 is rotated by rotating the key inserted from the key hole 14a on the left side in the figure, and the cylinder lock 1 can be unlocked or locked. For example, it can be used for a slot game table having a short depth or a slot game table having a long depth.

  Further, as shown in FIGS. 4 to 6, the inner cylinder 14 and the front connecting shaft 32 are concave portions provided on the cross section of the rear portion of the inner cylinder 14 asymmetry with respect to the rotation axis. Since the convex portions 32a-1 and 32a-2 provided at the front portion of the front connecting shaft 32 are respectively inserted and engaged with 14b-1 and 14b-2, the upper and lower portions of the inner peripheral cylinder 14 are connected. With respect to the direction, the front connecting shaft 32 is abutted by being regulated in a normal direction.

  Further, the front end portion of the connecting shaft 33 is inserted into and engaged with a shaft hole 32 b provided at the rear portion of the front connecting shaft 32 and provided asymmetry with respect to the rotation shaft. That is, as shown in FIGS. 5 and 6, the shaft hole 32 b is a substantially rectangular shape that is vertically long in the vertical direction in the figure, and further, on the upper part of the shaft hole 32 b in the figure, the downward direction is provided. A convex portion 32c is provided, and a curved surface portion 32d projecting downward is provided below the shaft hole 32b. Similarly, a concave portion 33a is provided on the upper surface of the connecting shaft 33 in the drawing, and a curved surface portion 33b is provided on the lower surface of the connecting shaft 33 in the drawing. Further, the shaft hole 32b is provided with rattling-preventing ribs 32e-1 and 32e-2, which are formed of minute convex portions that do not affect the insertion of the connecting shaft 33, on one longitudinal plane portion. When the connecting shaft 33 is inserted, the connecting shaft 33 and the front connecting shaft 32 are fixed by fixing the connecting shaft 33 at two points from one horizontal direction in the figure and by fixing the surface from the other direction. This prevents backlash.

  From such a configuration, the front connection shaft 32 is abutted by being regulated in a normal direction with respect to the vertical direction of the inner cylinder 14, and is further in a normal direction with respect to the vertical direction of the front connection shaft 32. Therefore, the connecting shaft 33 is inserted.

  Further, the rear end portion of the connecting shaft 33 is inserted into and engaged with a shaft hole 36 a provided at the front portion of the output shaft 36 and provided asymmetry with respect to the rotation shaft. That is, as shown in FIG. 4, the shaft hole 36 a is a substantially rectangular shape that is vertically long in the vertical direction in the figure, and further, a downwardly protruding portion 36 b is formed on the upper part of the shaft hole 36 a in the figure. And a curved surface portion 36c projecting downward is provided below the shaft hole 36a. Similarly, a concave portion 33a is provided on the upper surface of the connecting shaft 33 in the drawing, and a curved surface portion 33b is provided on the lower surface of the connecting shaft 33 in the drawing. Further, the shaft hole 36a is provided with rattling-preventing ribs 36d-1 and 36d-2 made of minute convex portions that do not affect the insertion of the connecting shaft 33 on one of the long flat portions. When the connecting shaft 33 is inserted, the connecting shaft 33 and the front connecting shaft 32 are fixed by fixing the connecting shaft 33 at two points from one horizontal direction in the figure and by fixing the surface from the other direction. This prevents backlash.

  With such a configuration, the front connection shaft 32 is restricted in the normal direction with respect to the vertical direction of the inner cylinder 14, and is regulated in the normal direction with respect to the vertical direction of the front connection shaft 32. Then, the connecting shaft 33 is inserted, and the rear end portion of the connecting shaft is inserted into the shaft hole 36a in a state where the connecting shaft 33 is regulated in a normal direction with respect to the vertical direction of the connecting shaft 33.

  As described above, each of the inner cylinder 14, the front connecting shaft 32, the connecting shaft 33, and the output shaft 36 has an abutting portion (insertion portion) that is asymmetric with respect to the rotation axis. It is configured.

  Therefore, for example, when the connecting shaft 33 is inserted into the shaft hole 32b of the front connecting shaft 32, as shown in the upper part of FIG. If the part 32d and the curved surface part 33b are inserted so as to be aligned and assembled, they can be inserted. However, as shown in the lower part of FIG. If the orientation is aligned and the curved surface portion 32d and the concave portion 33a are aligned, the convex portion 32c and the curved surface portion 33b interfere with each other so that they cannot be inserted. That is, the connecting shaft 33 cannot be inserted into the shaft hole 32 b of the front connecting shaft 32 in a state opposite to the regulated normal direction. Similarly, the connecting shaft 33 cannot be inserted into the shaft hole 36 a of the output shaft 36 in a state reverse to the regulated direction.

  Accordingly, the inner cylinder 14, the front connecting shaft 32, the connecting shaft 33, and the output shaft 36 are all in a state that can be assembled only in a state of being regulated in a normal direction with respect to the rotating shaft. At this time, for example, the output shaft 36 is not assembled in a state reverse to 180 ° with respect to the rotation shaft. As a result, when the output shaft 36 is assembled in a state reverse to 180 ° with respect to the rotation shaft, the joint block 38 and the concave portion 39b of the joint cam 39 are fitted even though the reset button 35 is not pressed. It is prevented that they are not matched.

  More specifically, for example, when the output shaft 36 is assembled in a 180 ° reverse state, the joint block 38 is pressed against the position where the joint block 38 exists even if the joint block 38 is pressed in the outer circumferential direction by the repulsive force of the spring 37. Since the recess 39b of the joint cam 39 exists on the opposite side of 180 °, even when the reset button 35 is not pressed, the joint block 38 cannot be fitted into the recess 39b, and the output shaft 36 The joint cam 39 cannot be connected (fixed). For this reason, even if the key rotates, the inner cylinder 14 rotates, the front connecting shaft 32 rotates, the connecting shaft 33 rotates, and further, the output shaft 36 is rotated by the connecting shaft. The joint block 38 cannot transmit the torque generated by the output shaft 36 to the joint cam 39, and the joint cam 39 is not rotated. As described above, after the assembly, there may occur an operational trouble that is not noticed until it is operated.

  However, according to the above-described configuration, the inner cylinder 14, the front connecting shaft 32, the connecting shaft 33, and the output shaft 36 can be assembled only in a state where they are regulated in a normal direction with respect to the rotating shaft. As a result, the output shaft 36 is assembled in the proper direction with respect to the joint cam 39, and it is possible to prevent operational troubles that are not noticed until the output shaft 36 is operated at the stage of assembly. . Also, if the cylinder lock is assembled at the time of assembly, the part insertion direction will be correct at that time, so it is not necessary to check every time after assembling whether the insertion direction is correct or not. It is possible to improve the work efficiency.

  In the above description, an example in which the inner peripheral cylinder 14 and the front connection shaft 32 are individually configured has been described. Therefore, the inner cylinder 14 and the front connecting shaft 32 may be integrated. As described above, since the inner peripheral cylinder 14 and the front connecting shaft 32 have an integral structure, the number of parts is reduced, so that the assembly work process can be reduced.

  In the above description, the connection shaft 33 has been described with respect to the case where the cross-sectional shape perpendicular to the rotation axis of the inner cylinder 14 is constant. However, the cross-sectional shape of the front end of the connection shaft 33 and the rear end These cross-sectional shapes do not necessarily have the same cross-sectional shape as long as they are asymmetrical with respect to the rotation axis. In that case, the cross-sectional shape of the shaft hole 32b of the front connection shaft 32 and the cross-sectional shape of the shaft hole 36a of the output shaft 36 correspond to the shapes of the front end portion and the rear end portion of each connection shaft 33. Need to be configured. Accordingly, the sectional shape of the shaft hole 32b of the front connecting shaft 32 and the sectional shape of the shaft hole 36a of the output shaft 36 are not necessarily the same.

  Furthermore, the relationship between the concaves and convexes of the front connecting shaft 32, the connecting shaft 33, and the output shaft 36 is not limited to the above relationship, and a convex portion is provided instead of the shaft hole 32b of the front connecting shaft 32. A concave portion corresponding to the convex portion of the front connecting shaft 32 is provided at the front end of the connecting shaft 33, and similarly, a convex portion is provided instead of the shaft hole 36 a of the output shaft 36. A concave portion corresponding to the convex portion of the output shaft 36 may be provided at the rear end, and in any case, as long as the cross-sectional shape is asymmetric with respect to the rotational axis and can be inserted. It ’s good.
