Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an alarm watch, and more particularly, to a wrist watch capable of setting an operation time of an alarm bell from a front side.

[0002]

[Prior art]

 A general analog clock mainly has a time display function, and a conventional alarm clock has an alarm bell function in addition to the time display. Regardless of the analog clock or the alarm clock, the hour hand and the minute hand are designed by design, respectively. The hour hand, minute hand tube, second hand tube, etc., which are coaxially installed at the center from outside to inside, are usually attached to the center hand, the second hand, etc., and the transition of time is displayed by the movement of each hand. In addition, since the alarm clock has the function of an alarm bell, in addition to the above hour hand tube etc., a member related to the alarm bell is arranged at the center and the outer periphery of the hour hand tube at the center is coaxial. A timer tube is fitted, and a related member that adjusts and rotates the timer tube to change the alarm bell set time is provided on the outer surface of the alarm watch case.

[0003] Usually, an alarm clock is not worn and carried like a wristwatch, and is almost always placed at a predetermined position. Therefore, an operation time setting member of an alarm bell and a mounting position thereof are relatively unrestricted. Generally, a rod-shaped rotary knob is provided at an appropriate position on the back of the watch for setting the operation time of the alarm bell. However, for example, when a wristwatch that can be carried around the wrist is provided with an alarm bell function, the location of the alarm bell operating time setting member is limited due to convenience considerations.

[0004] That is, if the alarm bell operating time setting member is provided on the back of the watch, not only can the high degree of waterproofness be maintained, but also the watch must be removed from the wrist when setting the alarm bell operating time. In addition, a concave portion is formed in the back cover of the watch, and the disk member is attached, which complicates the structure. On the other hand, it is conceivable to attach an alarm bell operating time setting member on the periphery of the case alongside the one for time adjustment, but the periphery of the case has already been used for the mainspring, time adjustment, stopwatch function, etc. Since a large number of members are provided, there is not much space.

[0005]

[Problems to be solved by the invention]

 The present invention has been made in view of the above problems, and has an object to provide an alarm bell operating time setting member on the watch surface side so that the alarm bell operating time can be set directly from the watch surface. It is assumed that.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a case having a hollow portion formed in a central portion thereof, and a time tube for setting an operation time of an alarm bell which is housed in the hollow portion of the case and is exposed at a central portion of an upper end surface thereof. And a body provided with a first locking portion, a first interlocking portion provided on an outer periphery, a shaft hole provided in a center portion, and a second locking portion protruding from a hole edge of the shaft hole. A time plate which is engaged with the first locking portion of the time tube correspondingly to the second locking portion and is rotatable integrally with the time tube; Then, a lower end portion having a second interlocking portion provided on an inner peripheral edge thereof is fitted into the hollow portion of the case, and the second interlocking portion is engaged with the first interlocking portion of the time plate so as to correspond to the first interlocking portion. And a rotating ring for interlocking rotation of the time plate when the upper end face is rotated. The present invention provides a watch capable of setting an alarm bell operating time on a surface characterized by the following.

[0007] With the above structure of a watch worn on a wristwatch or the like, when a rotating ring is rotated on the surface of the watch, a second interlocking portion of the rotating ring rotates the time plate in an interlocking manner, and the time plate is rotated. The operating time of the alarm bell can be set by rotating the time tube of the aircraft in conjunction. Therefore, the alarm bell activation time can be easily set without removing the watch from the wrist. In addition, by providing the time setting member on the watch front side, complicated processing required for installation on the back cover side is not required, the number of work steps can be reduced, and sweat on the wrist enters the watch from the back cover. Can also be solved.

The airframe has an elastic pawl protruding near an edge of an upper end surface thereof, and the rotating ring has a toothed ring portion of an uneven tooth array on an outer peripheral surface of a lower end portion thereof. Is preferably pressed by the elastic pawl.

[0009] The elastic pawl of the fuselage has a fixed end integrally connected to an upper end surface of the fuselage and a lead end which is elastically deformed when subjected to a force. It is preferable that the protruding portion is provided, and the locking tooth is brought into contact with the tooth ring portion of the rotating ring.

[0010] With the above configuration, the rotation ring can be prevented from rotating in the opposite direction to the correct direction, and problems such as damage to the internal clock mechanism due to the reverse rotation can be prevented. In addition, since the elastic pawl exerts an appropriate resistance on the rotation of the rotating ring, it is possible to prevent the alarm ring setting time from being changed carelessly, for example, when a force is applied to the rotating ring in daily operation.

[0011] Preferably, a time mark extending from the center to the periphery and a direction mark extending in an arc in a counter-clockwise direction with a required length are preferably provided on the surface of the time plate. Thereby, the set operation time of the alarm bell can be easily confirmed, and the direction sign can more reliably prevent an erroneous operation of the rotating ring.

It is preferable that a sliding piece protruding outward is provided around the body, and the sliding piece is moved to a different position to turn on / off the function of the alarm bell. In this way, the alarm bell function can be turned on and off without removing the watch from the wrist.

[0013]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 4 show a watch capable of setting the operation time of an alarm bell on the surface of the present invention, which is provided with an airframe 1, a time plate 2, a case 3, a rotating ring 4, a back cover 6, and the like.

The body 1 has a time tube 11 and an hour hand tube such as an hour hand tube, a minute hand tube, and a second hand tube, which are coaxially stacked from the outside to the inside at the center of the upper end face 10 so as to protrude. Is provided. The time indicating needle tubes such as the above hour hand tube, minute hand tube, and second hand tube are driven by a gear set provided in advance in the body 1, and the moving time of each time indicating needle tube is set to the time set by the timer tube 11. The related structure and operation form, such as the sounding of an alarm bell upon reaching, are the same as the structure of the conventional alarm clock, and thus the description is omitted.

A pair of groove-shaped first locking portions 111 are formed in the vicinity of the timer tube 11 at opposing positions. A sliding piece 12 slidable around the body 1 is projected outward. The sliding piece 12 activates a switch provided in the body 1 in advance, and pulls the sliding piece 12 to a different position so that the function of the alarm bell is turned on and off.

A pair of fixing grooves 13 having a required depth are provided on both sides corresponding to each other around the upper end surface 10 of the body 1. Further, a pair of elastic pawls 14 are provided on the upper end surface 10 adjacent to the fixing grooves 13 at positions corresponding to each other. The elastic pawl 14 includes a fixed end 141 integrally connected to the upper end face 10 and a lead end 142 that elastically deforms when subjected to a force. A locking tooth 143 protrudes from the inner end surface of the lead end 142. ing .

The thyme plate 2 is formed of a transparent material, and covers the upper end surface 10 in a shape corresponding to the upper end surface 10 of the body 1. The thyme plate 2 has a pair of opposing first interlocking portions 20 cut out and provided on the peripheral edge, and a shaft hole 21 is formed in the center. A second locking portion 22 is provided which protrudes inward relative to a hole edge of the shaft hole 21. In addition, a time mark 23 of a linear arrow extending from the center to the periphery and a direction mark 24 of an arc-shaped arrow extending in an arc of an appropriate length in the opposite hour hand direction are provided on the surface of the time plate 2. ing.

When the thyme plate 2 is covered on the upper end surface 10 of the body 1, the shaft hole 21 is fitted to the time tube 11 of the body 1, and the second locking portion at the hole edge of the shaft hole 21 is formed. The 22 and the first locking portion 111 of the time tube 11 are fitted and fixed, whereby the time plate 2 and the time tube 11 can be integrally and rotatably linked.

The case 3 is formed in an annular shape, and has a hollow portion 31 in the center portion in which the body 1 can be stored. Bearing portions 30 are provided at both ends extending from the periphery of the case, and a watch band (not shown) to be wound around the wrist is attached. A pair of opposing fixed blocks 32 project from the periphery of the hollow portion 31 of the case 3, and a ring edge 33 having a diameter slightly smaller than the body 1 is provided along the periphery of the upper end of the hollow portion 31. There. When the fuselage 1 is fitted into the hollow portion 31 from below and mounted, the fixing block 32 is fitted into the fixing groove 13 of the fuselage 1, and the upper end surface 10 is locked by the ring edge 33 and is held in a fixed position. Configuration. Further, a first locking ridge 331 is provided along the lower end of the inner surface of the ring edge 33 and protrudes in a thin strip shape.

The rotating ring 4 is formed in an annular shape, and a lower end portion of a peripheral edge thereof is shaped so as to be able to fit inside the hollow portion 31 of the case 3. As shown in FIG. 3, inner and outer ring projections 41 and 42 projecting inward and outward, respectively, are formed on the outer peripheral edge of the upper end portion. A protruding second interlocking portion 43 is provided on the inner surface of the lower end portion, and a tooth ring portion 44 for forming an uneven tooth row is provided on the outer surface. A second locking strip 47 projecting like a strip is provided.

The provision of the inner ring projection 41 prevents the glass cover 5 from being detached from the upper end surface of the rotating ring 4 when the transparent glass cover 5 is attached from below to above. Further, when the lower end of the rotating ring 4 is fitted into the hollow portion 31 of the case 3, the second locking striation 47 is urged downward from above to move the first locking striation 331 downward. , The rotation ring 4 can be prevented from coming off. The bottom edge 46 of the lower end of the rotating ring 4 substantially abuts on the upper end face 10 of the fuselage 1 and surrounds the whole of the time plate 2 inside. 4 and engages with the first interlocking portion 20 at the periphery thereof, and the state shown in FIG. 4 is obtained.

The tooth ring portion 44 on the lower end outer surface of the rotating ring 4 is elastically brought into contact with the locking teeth 143 of the elastic pawls 14 on the periphery of the machine body 1, as shown by a virtual line (two-dot chain line) in FIG. In addition, the elastic pawl 14 comes into contact with the toothed ring portion 44, and a required resistance is generated when the rotating ring 4 is rotated.

The upper end of the rotating ring 4 makes the outer ring projection 42 correspond to the upper end face of the ring edge 33 of the case 3. In addition, in order to easily rotate the rotating ring 4, a plurality of pairs of ribs 45 are provided at appropriate intervals on the upper end surface 40 of the rotating ring 4, and the rotating ring 4 can be rotated by pushing the ribs 45 with a finger. Like that. One of the ribs 45 extends to the outer edge 451 of the outer edge of the outer ring projection 42, and each corresponds to a position above the second interlocking portion 43. Accordingly, when the rotating ring 4 is fitted into the case 3, even if the second interlocking portion 43 is below and cannot be seen from the upper end surface, the second interlocking portion 43 is located at the position corresponding to the outer edge portion 451 of the rib 45. Since the position of the part 43 can be known, the work of fitting the second interlocking part 43 to the first interlocking part 20 of the time plate 2 becomes easy.

The back cover 6 is fixedly covered with the case 3 and the bottom of the body 1 which are integrally assembled, and supports and protects the body 1. By design, the bottom surface of the back cover 6 may be slightly concave to match the shape of the wrist, and an appropriate number of holes 61 may be provided on the entire back cover 6 to adjust the time from the holes 61 to the body 1. And battery replacement.

The related structure that is driven and rotated by the internal structure at the center, such as the timer tube, the hour hand tube, the minute hand tube, and the second hand tube, is the same as that of the related art, so that the description is omitted.

In the watch composed of the wristwatch assembled as described above, when the rotating ring 4 exposed on the watch surface is adjusted and rotated, the second interlocking section 43 of the rotating ring 4 rotates the time plate 2 in an interlocking manner. The time plate 2 can turn the time tube 11 of the body 1 by the second locking portion 22 at the center thereof to set the operation time of the alarm bell. The set operation time of the alarm bell can be known from the position indicated by the time mark 23 on the time plate 2. The direction sign 24 of the time plate 2 can indicate an accurate direction when the time plate 2 is rotated.

A related timing structure inside a time tube of this kind is that a time error occurs when the time tube is inserted and locked from the hour hand direction in a predetermined engagement relationship for sounding the alarm bell. Generally, most of them are inserted and locked from the counter-clockwise direction, and from this point, it is functionally excellent that the direction of rotation of the time plate 2 is accurately indicated by the direction display 24. Note that the direction of adjustment and possible errors that exist in the time mechanism exist in the related time structure of the conventional aircraft and are not a key part of the present invention, and therefore description thereof will be omitted.
