Since the baffle plate can be unlocked freely by pushing the operation end of the main body from the front side and back side to make it all small in diameter, no key is required, the structure is simplified, and the operation is further simplified. Also improved.

Embodiments of the present invention will be described below with reference to the drawings.
In the first embodiment, an embodiment of the invention described in claim 1 will be described.

  1 and 2, reference numeral 1 denotes a main body case. The main body case 1 is formed by connecting first and second shells 2 and 3 having a circular outer shape and a shallow dish shape with openings joined to each other. The baffle plate is integrally fixed by the rotating shaft 4 and has a flat box shape as a whole.

  Incidentally, both ends of the rotating shaft 4 in the illustrated embodiment have irregular (rectangular in the illustrated embodiment) cross-sections, and the same opening (numbered) opened in the center of the first and second shells 2 and 3. The two ends are crimped to prevent rotation of the first and second shells 2 and 3 around the rotation shaft 4.

  Although this is not an essential configuration of the present invention, in order to completely prevent the first and second shells from being rotated, as shown in FIG. 3, for example, at least one portion of the opening edge of the second shell 3 is used. It is good to form the recessed part engaged with this in the opening edge in the position which aligns the protrusion which is not numbered to the protrusion of the 1st shell 2, and join these in the state which meshed | engaged.

  A circular baffle plate 5 is rotatably fitted to the rotation shaft 4. In the illustrated embodiment, the baffle plate 5 is a short-cylinder flange itself having a large flange. The short cylinder is fitted to the rotating shaft 4 so that the collar 6 (see FIG. 2) is connected to the baffle plate 5 and the second baffle plate. The backlash in the length direction of the rotating shaft 4 of the baffle plate 5 is removed by fitting between the inner surfaces of the two shells.

  As shown in FIG. 1, ten tumbler holes 7, 7 are opened at equal intervals on the same circle on the outer peripheral portion of the baffle plate 5.

  Each tumbler hole 7 has a dharma shape in which a large-diameter hole and a small-diameter hole (both are not numbered) are connected in the circumferential direction. The angle at which the large-diameter hole and the small-diameter hole look at the rotating shaft 4 is Each tumbler hole 7 is set identically.

  On the other hand, in the illustrated embodiment, the outer surface of the first shell 2 is designated as the surface of the main body case 1. On the surface of the main body case 1, the expansion pattern is the same as the expansion pattern of the tumbler holes 7, 7. In this case, ten pin holes 8, 8 that penetrate the main body case in the thickness direction are formed at equal angular intervals on the same circle in which the tumbler holes 7, 7 are disposed.

  A number and characters for distinguishing a tumbler pin described later from other tumbler pins are marked on at least the surface side (upper side in FIG. 2) of the main body case (see FIG. 1).

  On the other hand, each pin hole 8 is formed with operation ends 9 (see FIG. 2) projecting from the front and back surfaces of the main body case 1 at both ends, and a large-diameter hole of a tumbler hole is formed in the central portion penetrating the tumbler hole 7. A tumbler pin 13 in which a large-diameter portion 11 to be fitted and a small-diameter portion 12 to be fitted to a small-diameter hole of the tumbler hole are continuously provided is movably fitted in the length direction, that is, the thickness direction of the main body case 1. .

  In the illustrated embodiment, the diameter of the small diameter portion 12 is set to be the same as that of the operation end 9, but this is not an essential component of the present invention.

In addition, although the pin hole 8 and the operation end 9 of the tumbler pin are fitted with each other in order to prevent the tumbler pin 13 from moving in the length direction due to weight, a so-called interference fit or a close fit is preferable. When operating the tumbler pins in such a manner that the main body case is raised and the tumbler pins 13 and 13 are horizontal, there is no problem even if they are loosely fitted.

  The tumbler pins are divided into two types, first and second tumbler pins. The two tumbler pins shown in FIG. 2 are both first tumbler pins. When the operation end 9 is pushed downward from the surface side (upper side), the first tumbler pins are as shown on the left side of FIG. The small diameter portion 12 is aligned with the baffle plate 5.

  However, when pushed from the back side, the large diameter portion 11 is aligned with the baffle plate 5 as shown on the right side of FIG.

  Similarly, it can be considered that the small diameter portion 12 is aligned with the baffle plate 5 when the operating end 9 is pushed from the back surface side, and the large diameter portion 11 is aligned with the baffle plate 5 when pushed from the front surface side, This is the second tumbler pin.

  In the illustrated embodiment, the position of the baffle plate 5 in the thickness direction of the main body case 1 is not in the center and is biased downward in FIG. 2, so the first and second tumbler pins have different shapes, but the baffle plate 5 Is the same in the thickness direction of the main body case 1, the first and second tumblers can have the same shape. At this time, the tumbler pins 13 are repeatedly fitted into the pin holes according to the first and second distinctions. Disguise.

  Further, the non-numbered large-diameter portion formed on the opposite side to the large-diameter portion 11 with respect to the small-diameter portion 12 of each tumbler pin 13 is used to define the pushing amount of the tumbler pin 13 in the illustrated embodiment. Yes.

  Then, the first tumbler pin is fitted into the selected pin hole group of the main body case 1 and the second tumbler pin is fitted into the remaining pin hole group, so as to make a so-called key difference.

  In this case, for example, if the first tumbler is fitted in the pin holes marked with the numbers 7, 5, 3 and 0 on the surface of the main body case, the remaining 1, 2, 4, 6, 8, and 9 A second tumbler pin is fitted in

  At this time, the password of the push-pull lock is stored as, for example, A-7530.

  Further, a hook portion is formed at the other end of the shackle 15, and at the time of locking, the other end is inserted into the main body case through the locking notch 16 formed at the opening edge of the second shell 3, and the hook portion is engaged. The opening notch 16 is retained at one opening edge.

  It should be noted that each of the locking notch 16 and the operating notch 17 through which the operating arm 14 is inserted keeps a gap in the clockwise direction, and when the baffle plate 5 moves clockwise as will be described later, the operating arm 14 or the shackle The other end should not interfere (see FIG. 1).

  The push-pull lock according to one embodiment of the invention described in claim 1 configured as described above pushes in, for example, all tumbler pins from the surface side during locking.

  Then, as shown in FIG. 1, the large-diameter portion of the tumbler pin is fitted into the large-diameter portion of the pin hole 8 corresponding to the numeral 9.

  Then, as is apparent from FIG. 1, the baffle plate 5 cannot move clockwise or counterclockwise, and this push-pull lock is in a locked state.

  Accordingly, as is apparent from FIG. 1, the collar portion at the other end of the shackle 15 is locked to the main body case 1, and this padlock keeps the locked state.

  When unlocking, for example, by pressing the back of the outer case against the surface of a hard object, all the tumbler pins are pushed in from the back side, and then the tumbler pins corresponding to the numbers 7, 5, 3 and 0 on the surface are pushed in. The small diameter part of the tumbler pin is aligned with the large diameter hole of the pin hole.

  Accordingly, when the main body case 1 is held in one hand and the shackle 15 is rotated clockwise in FIG. 1 with the other hand, the baffle plate 5 rotates relatively clockwise with respect to the main body case 1 as shown in FIG. The hook portion at the other end of the shackle is removed from the locking notch 16, and as a result, the shackle 15 can be rotated as indicated by the chain line, in other words, the padlock is unlocked.

  5 and 6 show a pin lock according to an embodiment of the present invention as set forth in claim 2, and, as described above, shows a case where it is applied to a padlock.

  In the pin lock shown in FIGS. 5 and 6, the password is not a number but a combination of alphabets.

  The invention according to claim 2 does not rotate the baffle plate but moves it linearly, and the outer case 1 is an elongated rectangular parallelepiped.

  In the embodiment shown in FIGS. 5 and 6, the first and second shells 2 and 3 are caulked by a pair of connecting shafts 18 and 18, and are formed along the length direction of the baffle plate 5. By the engagement between the guide slits 19 and 19 and the connecting shafts 18 and 18, the guide slits 19 and 19 are guided so as to be movable in the left-right direction in the drawing.

  An arrow-shaped U-shaped shackle 15 is integrally formed at the left end of the baffle plate 5, and when locked, the lower end in FIG. 5 is engaged with the slit of the outer case 1, and the padlock is locked. The shackle 15 moves outward as indicated by the chain line, and the padlock is unlocked.

  5 and 6, the same reference numerals as those in FIGS. 1 to 4 denote the same parts, and in FIG. 6, the reference numeral 20 denotes a retaining ring.

  FIG. 7 shows a tumbler pin according to an embodiment of the invention described in claim 3, and the invention described in claim 3 can arbitrarily convert one tumbler pin into first and second tumbler pins.

  That is, the tumbler pin 13 in FIG. 7 is configured by an operating portion 21 having operating ends 9 formed at both ends, and a cylindrical operating tube that is fitted to the outside of the operating portion 21 via frictional engagement. .

  As the friction engagement member 22 that makes this friction engagement, for example, a rubber O-ring or a C-shaped wire ring formed so as to strongly sandwich the operation portion 21 is suitable.

  And the small diameter part of the said tumbler pin is formed in the center part of a working cylinder, and the external shape of a working cylinder is made the same diameter as a large diameter part.
