Description

  The present invention relates to a learning watch used as a teaching material in an elementary school or the like.

  Conventionally, for example, a learning timepiece described in Patent Document 1 has been proposed as a learning timepiece used in learning about time. The learning timepiece described in Patent Document 1 includes a dial having a substantially disk shape, and a hand unit having a short hand as an hour hand and a long hand as a minute hand. The short hand and long hand constituting the needle unit are rotatable around a reference axis provided at the center of the dial.

  An hour scale and a minute scale are formed on the outer peripheral side of the dial. An auxiliary ring on which an hour scale and a minute scale corresponding to the hour scale and the minute scale formed on the dial are detachably attached to the outer peripheral edge of the dial. A pair of cursors are slidably provided on either the inner periphery or the outer periphery of the auxiliary ring. Of the pair of cursors, the first cursor corresponds to the short hand and the second cursor corresponds to the long hand. Time learning is performed using a pair of cursors and a needle unit.

  For example, the first cursor is placed at the “10 o'clock” position, and the second cursor is placed at the “5 minute” position. The short hand is arranged at the “11 o'clock” position, and the long hand is arranged at the “15 minute” position. In this state, the student is made to think about the time difference (in this case, 1 hour and 10 minutes) between the time pointed by the pair of cursors and the time pointed by the needle unit. The learning clock is also used to obtain a time (in this case, 10:30) C minutes (for example, 20 minutes) after A hour and B minutes (for example, 10:10). .

JP 2004-54171 A

  By the way, the pair of cursors are not provided in an actual clock. Therefore, in order to correctly read the time pointed by a pair of cursors, each cursor is replaced with a short hand and a long hand in the head, and the time is obtained based on the position pointed to by the replaced short hand and long hand. It is very difficult to make such thoughts to elementary school students (especially lower grade students). In other words, it is very difficult for an elementary school student (especially a lower grade student) to read the time pointed by a pair of cursors, and it has been difficult to say that the learning timepiece can appropriately assist time learning.

  The present invention has been made in view of such circumstances. The object is to provide a learning watch that can appropriately assist learning related to time.

  In order to achieve the above object, a learning timepiece according to the present invention covers a dial on which a plurality of hour scales and a plurality of minute scales are formed along a circumferential direction around a reference axis, and covers the dial. And a cover member made of a material that allows the dial to be visually recognized from the outside, and a first member that is disposed between the dial and the cover member and that rotates about the reference axis. A first time means having an hour hand and a first minute hand; and a second time means having at least one of a second hour hand and a second minute hand attached in a detachable manner to the cover member. This is the gist.

  According to the above configuration, the first time means has the first hour hand and the first minute hand, and the second time means has at least one of the second hour hand and the second minute hand. Yes. Therefore, the time point indicated by the second time means can be easily read by elementary school students (especially lower grade students). Accordingly, it is possible to appropriately assist time learning.

It is preferable that the learning timepiece of the present invention further includes support means that is provided at a position corresponding to the reference axis in the cover member and supports the second time means.
According to the above configuration, at least one of the second hour hand and the second minute hand constituting the second time unit is attached to the cover member while being supported by the support unit.

In the timepiece for learning according to the present invention, it is preferable that the support means supports the second time means in a detachable and rotatable state.
According to the above configuration, at least one of the second hour hand and the second minute hand constituting the second time means can be rotated while being attached to the cover member. Therefore, learning about time can be effectively assisted compared to the case where at least one of the second hour hand and the second minute hand attached to the cover member is not rotatable.

  In the learning timepiece of the present invention, the second time means includes the second hour hand and the second minute hand, and the second hour hand and the second minute hand are associated with the support means. It is preferable that the latching | locking part to be stopped is formed, respectively.

According to the said structure, a 2nd hour hand and a 2nd minute hand are attached to a cover member, when those latching | locking parts are latched by a support means.
In the learning timepiece of the present invention, the second time means has the second hour hand and the second minute hand, and protrudes toward the support means at a proximal end of the second minute hand, A supported convex portion that is latched by the supporting means is formed, and a latched portion that is latched by the supported convex portion of the second minute hand is formed at the proximal end of the second hour hand. Preferably it is formed.

  According to the above configuration, the second hour hand and the second minute hand are integrated by locking the locked portion of the second hour hand to the supported convex portion of the second minute hand. The integrated second hour hand and second minute hand are attached to the cover member by the supported convex portion being locked to the support means.

  In the learning timepiece according to the aspect of the invention, the second time unit further includes an adsorption portion that is detachably attached to the cover member, and at least one of the second hour hand and the second minute hand is It is preferably supported in a rotatable state with respect to the adsorption part.

(First embodiment)
Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the learning timepiece 11 of the present embodiment includes a main body case 12 made of synthetic resin. On the front side (the left side in FIG. 2) of the main body case 12, a concave portion 13 having a substantially circular shape in plan view is formed. In the main body case 12, a receiving portion 14 (shown by a broken line in FIG. 1) is formed on the rear side of the bottom portion of the recess 13. The accommodating portion 14 is formed from the center at the bottom of the concave portion 13 toward the upper right in FIG. A through hole 15 is formed in the center of the bottom portion 26 a of the recess 13 to communicate the inside and outside of the housing portion 14. Further, a first communication hole (not shown) for communicating the inside of the housing portion 14 with the outside is formed on the side wall of the main body case 12 obliquely to the right in FIG. Further, a second communication hole 16 (see FIG. 3) for communicating the inside of the recess 13 and the outside is formed on the side wall of the main body case 12 diagonally to the left in FIG.

  An annular display plate 17 made of synthetic resin is accommodated in the recess 13 in a rotatable state. On the front surface of the display plate 17, minute numbers (0, 5,... 50, 55) Af in minute units are printed at equal intervals along the circumferential direction. An operation knob 18 that is disposed at the same position as the second communication hole 16 in the circumferential direction is attached to the display plate 17. Then, when the operation knob 18 is operated by the user, the display plate 17 rotates based on the operation.

  A circular dial 19 made of cardboard is bonded to the bottom of the recess 13. The dial 19 is disposed on the front side of the display plate 17. Twelve notches 20 are formed at equal intervals along the circumferential direction on the periphery of the dial 19. The fractional numbers Af printed on the display plate 17 can be visually recognized from the outside through the notches 20.

  In addition, on the front surface of the dial 19, four divisional scales Bf arranged at equal intervals along the circumferential direction are printed between the notches 20 adjacent to each other in the circumferential direction. In addition, hour numbers (1, 2,..., 11, 12) Bz in units of one hour are printed at equal intervals along the circumferential direction on the front side of the dial 19 and radially inward of the notches 20. Yes. At this time, the number Bz corresponds to the hour scale.

  A gear mechanism 21 (indicated by a two-dot chain line in FIG. 2) is accommodated in the accommodating portion 14. The gear mechanism 21 includes a first rotating shaft 22A as an example of a reference shaft protruding forward from the center of the dial 19, and a substantially cylindrical shape having the first rotating shaft 22A as an axis center. The second rotating shaft 22B having the cylindrical portion is coupled in a state where power can be transmitted. Each of these rotating shafts 22A, 22B passes through the through hole 15 of the recess 13, and the distal ends of the rotating shafts 22A, 22B are located outside the accommodating portion 14. However, the tip end of the first rotation shaft 22A is positioned in front of the tip end of the second rotation shaft 22B.

  A first short hand 23 as an example of a first hour hand is attached to the tip (front end) of the second rotation shaft 22B, and the second tip (front end) of the first rotation shaft 22A is second. A first long hand 24 as an example of the minute hand is attached. Therefore, in the present embodiment, the first time hand 23 and the first long hand 24 constitute a first time means. In addition, it is preferable that the 1st short hand 23 and the 1st long hand 24 are colored with a mutually different color.

  In addition, an operation drum 25 disposed obliquely above and to the right of the gear mechanism 21 in FIG. 1 is connected to the gear mechanism 21 in a state where power can be transmitted. Most of the operation drum 25 is accommodated in the accommodating portion 14, while a part of the operation drum 25 protrudes outside from the main body case 12 through the first communication hole. When the user rotates the operation drum 25, the driving force generated by the operation drum 25 is transmitted to the first short hand 23 and the first long hand 24 via the gear mechanism 21 and the rotation shafts 22A and 22B. The As a result, the first short hand 23 and the first long hand 24 rotate around the first rotation shaft 22A. The first short hand 23 rotates by 30 ° when the first long hand 24 rotates 360 °.

  Further, a bottomed substantially cylindrical cover member (also referred to as “lens”) 26 that covers the dial 19 is provided on the front side of the main body case 12. The cover member 26 is made of a transparent material so that the dial 19, the first short hand 23, and the first long hand 24 can be visually recognized from the outside even when the cover member 26 is attached to the main body case 12. Has been. Such a cover member 26 has a substantially disk-shaped bottom portion 26a and a cylindrical portion 26b located on the rear side of the bottom portion 26a. A support hole 28 having a substantially circular shape in plan view and a substantially ring-shaped protrusion 29 surrounding the support hole 28 are formed at the center of the bottom portion 26a of the cover member 26, that is, at a position corresponding to the rotation shafts 22A and 22B. The support part (support means) 30 which has is provided.

  As shown in FIG. 2, the support 30 includes a second short hand (second hour hand) 31 and a second long hand (second minute hand) that are separate from the first short hand 23 and the first long hand 24. ) 32, and a separate needle unit 33 as second time means can be supported. The second short hand 31 is colored in the same color as the first short hand 23 or a color close to the color of the first short hand 23, and the second long hand 32 is the same color as the first long hand 24 or the first color. It is colored in a color close to the color of the long hand 24. As shown in FIG. 3, an operation knob 34 that is operated by the user protrudes from the front side of the base end 32 a of the second long hand 32. Further, on the rear side of the base end 32 a of the second long hand 32, a supported convex portion 35 that is detachably inserted into the support hole 28 of the support portion 30 is projected. The proximal end 31 a of the second short needle 31 is formed with a substantially annular locked portion 36 through which the supported convex portion 35 of the second long needle 32 passes.

  When the separate needle unit 33 is attached to the cover member 26, the supported convex portion of the second long needle 32 is inserted into the locked portion 36 of the second short needle 31, and the second short needle 31. And the second long hand 32 are integrated. Then, the supported convex portion 35 of the second long hand 32 is inserted into the support hole 28 of the cover member 26. That is, the separate needle unit 33 is attached to the cover member 26 via the support portion 30. Thus, the second short hand 31 and the second long hand 32 attached to the cover member 26 are individually rotatable around the supported convex portion 35.

  As shown in FIG. 4, when the second short hand 31 is installed at the “11 o'clock” position and the second long hand 32 is installed at the “00 minute” position, It can be easily read that the time indicated by the hand unit 33 is 11:00. This is because it is not necessary to replace each cursor with a short hand and a long hand in the head, unlike when a pair of cursors is used to indicate the time. In addition, when 12:15 is pointed by the first short hand 23 and the first long hand 24, the time difference from the time (11:00) indicated by the second short hand 31 and the second long hand 32 is calculated. The user can think using the learning clock 11.

  In addition, for example, when the time after 15 minutes from 11:00 is to be obtained, the user points to 11:00 with the second short hand 31 and the second long hand 32 and the first short hand 23 and the first long hand Even the long hand 24 points to 11:00. In this state, the user rotates the position of the first long hand 24 from 00 minutes to 15 minutes later (in this case, 15 minutes). Then, the user reads the time pointed to by the first short hand 23 and the first long hand 24 (in this case, 11:15).

Therefore, in this embodiment, the following effects can be obtained.
(1) The separate needle unit 33 has a second short needle 31 and a second long needle 32. Therefore, compared with the conventional case using a pair of cursors instead of the separate needle unit 33, the time pointed by the separate needle unit 33 can be easily read by elementary school students (especially lower grade students). Accordingly, it is possible to appropriately assist time learning.

  (2) The conventional method of indicating the time using a pair of slidable cursors on the outer peripheral side of the dial 19 is a method that is not described in a textbook used in elementary school class or the like. Therefore, elementary school teachers and students need to use conventional learning watches after understanding how to use the cursor. However, pointing the time using a pair of cursors is a task that is not familiar to people in normal life. In this regard, in the present embodiment, the second short hand 31 and the second long hand 32 indicate the time instead of the pair of cursors. Pointing the time with the short hand and long hand is a very familiar task in normal life. Therefore, it can be said that the learning clock 11 of the present embodiment is a clock that is very easy to handle for elementary school students (especially lower grade students). Moreover, since the method of indicating time with the short hand and the long hand (in this case, the second short hand 31 and the second long hand 32) is a method described in the textbook, it can appropriately assist learning related to time.

  (3) The separate needle unit 33 of this embodiment is detachable from the cover member 26. Therefore, the time at two times (for example, 12:10 and 12:40) is obtained, or the time after A minute (for example, 20 minutes) from the first time (for example, 12:10) is obtained. For example, the separate needle unit 33 may be attached to the cover member 26. On the other hand, when learning to read the time is performed, the separate needle unit 33 is unnecessary, and therefore, the separate needle unit 33 that is no longer necessary may be removed from the cover member 26. That is, the separate needle unit 33 can be attached to or removed from the cover member 26 according to the learning content.

  (4) The second short hand 31 and the second long hand 32 attached to the cover member 26 are rotatable. Therefore, the time pointed to by the separate needle unit 33 can be changed in a state of being attached to the cover member 26, and thus learning related to time can be more appropriately assisted.

  (5) Integrating the second short hand 31 and the second long hand 32 by engaging the locked portion 36 of the second short hand 31 with the supported convex portion 35 of the second long hand 32. Can do. Therefore, when the second short hand 31 and the second long hand 32 are not used, the second short hand 31 and the second long hand 32 can be stored in an integrated state.
