Description

  The present invention relates to a dial-type padlock that can be unlocked by operating a plurality of dials to match a plurality of numeric strings with a preset numeric string.

  A typical window consists of a window frame in which an aluminum frame material is formed in a rectangular shape, and an inner window and an outer window that are fitted in the window frame so as to be openable and closable in a lateral direction, and a glass plate is fitted in both the windows. However, a crescent lock comprising a metal receiver attached to the vertical window of the outer window and a latch rotated by an operating lever attached to the vertical window of the inner window is used as the locking means.

  An intruder, such as a thief, sometimes broke the glass of the crescent lock part of the sliding window, turned the operation lever to unlock the crescent lock, and opened the sliding window.

  Thus, a dial type crescent lock provided with a lock device in which a dial type padlock is applied to the crescent lock is disclosed in Patent Document 1 below.

Japanese Patent No. 2576000

  The conventional dial padlock is fixed to the numeric string set at the time of manufacture, and can be unlocked only when it matches the numeric string. This numeric string cannot be changed. It is conventionally known that the value can be changed.

  When applying crescent locks with locking devices to multiple windows in a residence, especially when multiple family members live, all crescent locks have the same numeric string, and those numeric strings have changed It is hoped that it cannot be done.

  When a crescent lock with a locking device is attached to each window in each residential area of the apartment, the numeric strings differ for each residential area, and the numerical strings for multiple windows are the same in each residential area. There must be.

  In order to receive an order for a crescent lock that cannot change such a numeric string, it was necessary to assemble a numeric string desired by the resident after the order was received.

  In particular, in a condominium with a large number of residential areas, when receiving orders for multiple sets of crescent tablets with different numeric strings for each residential area and the same numeric string within each residential area, there are 10 types of numbers 0-9. I had to assemble it by selecting from dial wheels.

  As described above, the crescent lock of the numeric string desired by the customer is assembled after receiving an order, and thus cannot be prepared in advance. Therefore, the present invention has been conceived to solve such a problem.

The dial-type padlock of the present invention has a main body, a pipe member that is slidable in the axial direction in the main body and is non-rotatable, and a plurality of protrusions formed on the outer periphery, and one end portion is inserted into the pipe member In the dial type padlock, which is provided with a plurality of ring members and a plurality of dial rings fitted and inserted into the pipe member, so that a part of the outer periphery is exposed from the main body.
Each dial ring is concentrically divided into an outer ring and an inner ring, the inner ring is fitted into the outer ring, numerals are engraved on the outer periphery of the outer ring, A notch groove through which a protrusion formed on the outer periphery of the pipe member can pass is formed, and after setting the angular relationship between the outer ring number of the outer ring and the notch groove on the inner periphery of the inner ring, the outer ring An instantaneous adhesive having good fluidity is hung in a gap between the inner circumference of the inner ring and the outer circumference of the inner ring, and the outer ring and the inner ring are fixed and integrated.

  According to the dial type padlock of the present invention, the dial ring is concentrically divided into the outer ring and the inner ring and fitted together, and the angular relationship between the outer ring outer ring number and the inner ring inner notch groove is assembled. Since it is configured so that it can be set later, a large amount of semi-finished products that have undergone a complicated assembly process are prepared in advance, and the angular relationship between the dial wheel numbers and the notch grooves is set in the setting process before shipment. Therefore, it is possible to deal with orders for large numbers of large numbers.

  In addition, since the dial ring can arbitrarily set the positional relationship between the engraved numerals and the notch grooves, it is possible to set up one kind of dial rings of numbers 0 to 9 without preparing a large amount like the conventional padlock. It is convenient for inventory management of parts because it is only necessary to prepare different types.

The perspective view of the dial wheel and components used with the dial type padlock of this invention, Sectional drawing of the dial wheel and parts shown in FIG. A plan view, a sectional view and a bottom view of the dial ring shown in FIG. Sectional drawing of the dial wheel and components which show other embodiment, The perspective view used in order to explain the number setting process of the dial type padlock of this invention, The perspective view which shows the conventional crescent lock which has the locking device which applied the dial type padlock, Longitudinal section of dial padlock, It is an assembly drawing of the main parts in a dial type padlock.

  As shown in the perspective view of FIG. 6, a conventional dial-type crescent lock in which a dial-type padlock is applied to the crescent lock disclosed in the above-mentioned Patent Document 1, a window frame in which an aluminum frame member is formed in a rectangular shape, It consists of an inner window and an outer window that are fitted in a window frame so as to be openable and closable in the horizontal direction, and a glass plate 95 is fitted into both windows, and a receiver 94 attached to a vertical rod 92 of the outer window; , And a latch 93 attached to the vertical window 91 of the inner window.

  In the dial-type crescent lock, the latch 93 is integrated with the dial-type padlock 1 attached to the vertical shaft 91 via the base 96, and is rotated about the shaft 97. Used as unlocking means.

  As shown in the sectional view of FIG. 7 and the assembly drawing of FIG. 8, the conventional dial type padlock 1 is inserted into the cylindrical hollow portions 22a and 22b of the main body so as to be slidable in the axial direction thereof. A groove 23 is formed on the outer periphery of the pipe member 2 in the axial direction, and the protrusion 24 formed on the main body is engaged with the groove 23, so that the pipe member 2 moves in the axial direction. It is configured not to rotate.

  And in this pipe member 2, the long bar 31 of the rod-shaped piercing member 3 shape | molded by J shape is rotatably inserted, and the pipe member 2 is inserted into both ends at the lower end part and the intermediate part. A step portion 34 and a flange portion 35 are provided so as to be sandwiched from the pipe member 2 so that the J-shaped yoke member 3 does not come out of the pipe member 2, and the yoke member 3 is rotatably held by the pipe member 2. Has been. Further, on the outer periphery of the pipe member 2, projections 21a, 21b, 21c are formed at three locations.

  The main body of the dial padlock 1 has notch windows 11a, 11b, and 11c (see FIG. 6) at three positions at equal intervals, and the notch windows 11a, 11b, and 11c are exposed so that a part of the outer periphery is exposed. The individual dial wheels 5 a, 5 b, 5 c are inserted through the pipe member 2.

  On the outer circumference of the dial wheels 5a, 5b and 5c, numerals 0 to 9 are imprinted at equiangular intervals. Cutout grooves 58a, 58b, and 58c are formed in the inner holes 56a, 56b, and 56c of the dial wheels 5a, 5b, and 5c so that the protruding portions 21a, 21b, and 21c of the pipe member 2 can pass therethrough. The positions of these cutout grooves 58a, 58b, 58c are associated with the positions of the numbers stamped on the outer periphery.

  Further, the pinning member 3 protrudes from the hole 27 provided in the dial padlock 1 and the tip 33 of the short bar 32 bent into a J-shape is inserted into and removed from the hole 90 provided in the base 96. It is possible.

  The dial-type padlock configured as described above is operated by rotating the exposed outer peripheral portion of the dial wheels 5a, 5b, and 5c with a fingertip, so that the dial numbers 5a, 5b, and 5c are notched. The grooves 58a, 58b, and 58c are respectively aligned with the projections 21a, 21b, and 21c of the pipe member 2.

  As described above, when all of the cutout grooves 58a, 58b, and 58c of the inner holes 56a, 56b, and 56c are aligned with the positions of the protruding portions 21a, 21b, and 21c of the pipe member 2, the pipe member 2 can move in the axial direction thereof. Therefore, when the pulling member 3 is pulled, it moves together with the pipe member 2, and the projections 21a, 21b, 21c of the pipe member 2 enter the notch grooves 58a, 58b, 58c of the dial ring.

  Since the pinning member 3 is rotatably inserted into the pipe member 2, the tip 33 of the short bar 32 of the pinning member 3 has come out of the hole 27 and the hole 90 in the unlocked state. The yoke member 3 can be turned. At this time, the projection 24 of the main body is engaged with the groove 23 (see B in FIGS. 7 and 8) of the pipe member 2, and the pipe member 2 is configured to be unrotatable within the main body. However, the pipe member 2 does not rotate.

  When used as a normal dial padlock 1, turn the crown member 3 in the unlocked state to align the tip 33 with the hole 27 in the main body 1, and push the crown member 3 to insert the tip 33 into the hole 27. Then, the pipe member 2 also moves together with the yoke member 3, and the protrusions 21a, 21b, 21c of the pipe member 2 are located outside the notch grooves 58a, 58b, 58c of the dial wheel 5.

  Therefore, the dial member 5a, 5b, 5c is rotated to an arbitrary number string and the notch grooves 58a, 58b, 58c are displaced from the projections 21a, 21b, 21c, so that the pulling member 3 can be pulled and the pipe member The two protrusions 21a, 21b, and 21c hit the side surfaces of the dial wheels 5a, 5b, and 5c, and the pulling member 3 cannot be pulled, resulting in a locked state.

  Since the pipe member 2 cannot rotate because the projection 24 of the main body and the groove 23 of the pipe member 2 are engaged, the pipe member 2 does not rotate even if the crown member 3 is rotated, and the dial wheel 5a. Neither 5b nor 5c rotates. That is, since the positions of the projections 21a, 21b, 21c of the pipe member 2 in the rotational direction do not move, the unlocking number set in advance by the dial wheels 5a, 5b, 5c will not change even if the crown member 3 is rotated. Absent.

  In the conventional dial padlock described above, a dial ring is selected and assembled in advance so as to form a desired number string. Therefore, the number string could not be changed after assembly.

  Therefore, in the dial padlock according to the present invention, as shown in the perspective view of FIG. 1, the cross-sectional view of FIG. 2, the plan view A, and the bottom view C of FIG. It is divided into 45 and wheel. A concentric stepped portion 43 is formed on the inner periphery of the through hole 42 of the outer ring 41, and the inner ring 45 is rotatably fitted in the through hole 42. Further, a stepped portion 47 is formed concentrically on the outer periphery of the bottom portion of the inner ring 45.

  When the inner ring 45 is fitted into the outer ring 41, a ring-shaped space is formed between the inner periphery of the through hole 42 of the outer ring 41 and the step portion 47 of the inner ring 45. Then, a C-shaped ring 49 in which the wire is bent round is fitted. The inner ring 45 can be held so as not to fall out of the outer ring 41 by the elasticity of the C-shaped ring 49 to expand.

  As shown in FIGS. 1 to 3, the through hole 46 of the inner ring 45 is formed with a notch groove 48 through which the projecting portions 21 a, 21 b, 21 c of the pipe member 2 can pass. Are engraved with numbers 0 to 9 at equiangular intervals.

  The dial type padlock of the present invention is substantially the same as the conventional dial type padlock described based on Patent Document 1 except for the dial wheel 4.

  As shown in the sectional view of FIG. 7, the dial-type padlock main body 1 has a pipe member 2 inserted through cylindrical hollow portions 22 a and 22 b so as to be slidable in the axial direction. A groove 23 is formed on the outer periphery in the axial direction, and the pipe member 2 moves in the axial direction by engaging with a protrusion 24 formed on the main body of the groove 23, but is configured not to rotate. Yes.

  In the pipe member 2, a long bar 31 of a rod-shaped piercing member 3 molded into a J-shape is rotatably inserted, and the pipe member 2 is inserted into the lower end portion and the intermediate portion from both ends. The step portion 34 and the flange portion 35 are provided so as to be sandwiched so that the J-shaped pulling member 3 does not come out of the pipe member 2, and the pulling member 3 is held by the pipe member 2. Further, projections 21a, 21b, and 21c are formed at three locations on the outer periphery of the pipe member 2.

  The main body 1 has three cutout windows 11a, 11b, 11c at equal intervals in three places, and three dial wheels 4a, 4b so that a part of the outer periphery is exposed from the cutout windows 11a, 11b, 11c. 4c is inserted through the pipe member 2 and held.

  As shown in an enlarged perspective view in the perspective view of FIG. 5, the side surfaces of the dial wheels 4a, 4b, and 4c are exposed from the cutout windows 11a, 11b, and 11c, and the upper and lower circles of the dial wheels 4a, 4b, and 4c are exposed. Part of the plane is also exposed.

  In particular, when the dial wheel 4 according to the present invention is applied, the ring-shaped space formed between the inner periphery of the outer ring 41 and the step 47 of the inner ring 45 and the C-shaped ring 49 are also exposed.

  When the three dial wheels 4 configured in this manner are fitted into the pipe member 2 and the outer ring 41 is rotated, the inner ring 45 is also rotated by friction, so that the inner ring 45 is operated by operating the outer ring 41. When the pipe member 2 is inserted so that the notch groove 48 of each inner ring 45 is aligned with the protrusions 21a, 21b, 21c of the pipe member 2 by rotating, the notch groove 48 of the inner ring 45 and the protrusion part of the pipe member 2 are inserted. The relationship with 21a, 21b, 21c is set to a state where unlocking is possible. At this time, the number indicated by the outer ring is indefinite.

  In this way, the three dial wheels 4a, 4b, 4c and the pipe member 2 are set in an unlockable state (a state in which the J-shaped pulling member 3 is pulled out) and incorporated in the main body, and the final setting process is performed. Without making it as an unfinished product. In such an unfinished product, even if the dial wheels 4a, 4b, and 4c are rotated, only the outer wheel 41 is rotated and the inner wheel 45 is not rotated.

  When a specific three-digit number is designated by the customer and an order is received, a final number setting process is performed and completed. In this number setting step, first, the semi-finished dial wheels 4a, 4b and 4c are turned to match the outer ring with the number designated by the customer.

  Then, as shown in FIG. 5, when a drop of a viscous adhesive with a low viscosity and good fluidity is dropped from a thin tube into an exposed ring-shaped space including the outer ring 41 and the C-shaped ring 49, the outer ring 41 and The instantaneous adhesive permeates into the gap with the inner ring 45 by capillarity and solidifies and adheres, so that the outer ring 41 and the inner ring 45 can be integrated into a finished product. This final number setting process can be completed in a shorter time than the assembly process.
