　本考案は、時計機能を有すると共に意匠的美感を兼ね備え、特にその文字盤前方に設けられた複数の扉片を開閉するものに関する。 (4) The present invention relates to a device having a clock function and a design aesthetic, particularly, a device for opening and closing a plurality of door pieces provided in front of the dial.

　最近、腕時計は単に時刻表示機能を有するだけではなく、使い易さや美感又はファション性を有するものが極めて多く発案されている。その数例として、特許文献１、特許文献２及び特許文献３等が上げられる。 Recently, many watches have not only a time display function but also ease of use, beauty, and fashionability. Patent Document 1, Patent Document 2, Patent Document 3, etc. are given as several examples.

　特許文献１に開示する「運転者用腕時計」は、指針および文字盤の位置が逆位置に回動し得る回転ベゼルと、それに蝶番結合する鏡面付きの蓋を有するものからなる。これにより、任意の姿勢状態で時間を正確に目視し得るようにしたものである。 The "driver's wristwatch" disclosed in Patent Document 1 includes a rotating bezel that allows the hands and the dial to rotate to opposite positions, and a mirror-finished lid hinged to the rotating bezel. Thus, the time can be visually observed accurately in an arbitrary posture state.

　特許文献２に開示する「裏返し文字盤時計」は、時計本体に上蓋を設置し、該上蓋内に設けた凸面鏡に文字盤上の時刻表示を裏返し表示するようにして文字盤の見易さを図ったものである。 Patent Document 2 discloses an "inverted dial timepiece", in which an upper cover is installed on a clock main body, and a time display on the dial is turned over on a convex mirror provided in the upper cover to improve the visibility of the dial. It is intended.

　また、特許文献３に開示する「腕時計」は、文字盤を保護する蓋付のもので、該蓋を腕時計本体からヒンジを介して取付するが、その反対側にヒンジ取付部と同形状の突起部を形成し、全体として左右対称形状としたため、ヒンジ部分の突起部による違和感がなくなり、左右のいずれの手首に対しても同様の意匠的態様に着用することができる。 The "watch" disclosed in Patent Document 3 has a cover for protecting the dial, and the cover is attached to the watch body via a hinge, and a projection having the same shape as the hinge attachment portion is provided on the opposite side. Since the portions are formed to be symmetrical as a whole, there is no sense of incongruity due to the projecting portions of the hinge portions, and it is possible to wear the same design on any of the left and right wrists.

実開昭５９−１１２１７０号公報（第１頁、第３図）JP-A-59-112170 (page 1, FIG. 3) 実開昭６０−０７９１８６号公報（第１頁、第１図、第４図、第５図、第７図）Japanese Utility Model Publication No. 60-079186 (Page 1, FIG. 1, FIG. 4, FIG. 5, FIG. 7) 登録実用新案第３０１６５７９号公報（第１頁、第１−３図）Registered Utility Model No. 3016579 (Page 1, FIG. 1-3)

　上述した公知技術はそれぞれに特徴を有するものであり、便利性や意匠的な美感を生じさせるものである。しかしながら、腕時計に付加する美的要素は常に多様的に変化し得るものが要求される。つまり、基本的には美感を刺激し意匠性を有することが必要である。さらに、腕時計の機能としての操作性が不可欠であり、且つコンパクトな形状のものが求められる。公知 The above-mentioned known techniques have their own characteristics, and provide convenience and aesthetically pleasing appearance. However, an aesthetic element added to a wristwatch is required to be constantly changing. That is, it is basically necessary to stimulate aesthetics and have a design. Further, operability as a function of a wristwatch is indispensable, and a wristwatch having a compact shape is required.

　本考案は、以上の事情に鑑みて考案されたものであり、意匠的な美感を有し、操作性が簡単で、且つコンパクトな形状に完成された腕時計を提供することを目的とする。 The present invention was devised in view of the above circumstances, and has an object to provide a wristwatch that has aesthetic appearance, is easy to operate, and is completed in a compact shape.

　上記課題を解決するためにこの考案が採った手段は、時計本体の時刻を表示する文字盤と、該文字盤を前方で覆う蓋体とを有し、その蓋体を開閉自在とした腕時計であって、文字盤の周縁部には少なくとも２枚の扉片をそれぞれ対向させて枢着し、開蓋時には２枚の扉片を付勢力により文字盤から離隔させて全開状態にすることで文字盤を現し、閉蓋時には２枚の扉片を付勢力に逆らって全閉状態にすることで蓋体の表面上に形成した模様を現したことを特徴とする。 Means adopted by the present invention to solve the above problem is a wristwatch that has a dial that displays the time of the watch main body and a lid that covers the dial in front, and the lid can be freely opened and closed. At least two door pieces are pivotally attached to the periphery of the dial so as to face each other, and when the lid is opened, the two door pieces are separated from the dial by an urging force to make the dial fully open. A feature is that a pattern is formed on the surface of the lid by bringing the two door pieces into a fully closed state against the urging force when the lid is closed.

　また、２枚の扉片は互いに対向させて閉じたときに、その扉片は互いに重なり合う部分がなく面一の状態で文字盤の前方に広がって文字盤の蓋体としての役目をする。 (4) When the two door pieces are closed to face each other, the door pieces spread out in front of the dial without any overlapping portions and serve as a cover of the dial.

　また、開蓋させる時は時計本体周囲に突出したつまみを有する係止部材を回転させて枢着部の付勢力を解放することにより２枚の扉片を開き、閉蓋させる時は開いた扉片を付勢力に逆らって文字盤方向に押付けて係止部材に係止させるようにする。 When the cover is opened, the locking member having a knob protruding around the timepiece body is rotated to release the urging force of the pivot portion, and the two door pieces are opened. When the cover is closed, the open door is opened. The piece is pressed in the dial direction against the urging force to be locked by the locking member.

　また、開蓋時には２枚の扉片が文字盤に対して垂直状態に枢着し、文字盤上に形成した模様が現れるようにする。 (4) At the time of opening the lid, the two door pieces are pivotally mounted vertically to the dial so that the pattern formed on the dial appears.

　また、時計本体周囲に突出したつまみにはその端面部を回転しやすいように滑り止めを施してある。つ In addition, the knob protruding around the watch body is provided with a non-slip so that the end face can be easily rotated.

　以上説明してきたように、この考案によれば、その構成を文字盤の周縁部には少なくとも２枚の扉片をそれぞれ対向させて枢着し、開蓋時には２枚の扉片を付勢力により文字盤から離隔させて全開状態にすることで文字盤を現し、閉蓋時には２枚の扉片を付勢力に逆らって全閉状態にすることで蓋体の表面上に形成した模様を現したため、開閉蓋のどの状態においても形成した模様を現すことができるという効果が得られる。 As described above, according to the present invention, at least two door pieces are pivotally attached to the peripheral portion of the dial face to face each other, and when the lid is opened, the two door pieces are biased by the urging force. Because the dial was revealed by separating it from the dial and fully opened, and when the lid was closed, the two door pieces were fully closed against the urging force to show the pattern formed on the surface of the lid The effect that the formed pattern can be displayed in any state of the opening / closing lid can be obtained.

　また、扉片は互いに閉じたときに文字盤の蓋体となり、互いに重なり合う部分がないため、文字盤の表面に形成された模様が一枚のものとして認識することができるという効果が得られる。 Furthermore, since the door pieces become lids of the dial when they are closed to each other, and there are no overlapping portions, the effect that the pattern formed on the surface of the dial can be recognized as a single piece is obtained.

　また、開蓋時には時計本体周囲に突出したつまみを有する係止部材を回転させて枢着部の付勢力を解放することにより扉片を開き、閉蓋時には開いた扉片を付勢力に逆らって文字盤方向に押付けて係止部材に係止させるようにしたため、簡単に手で蓋の開閉ができるという効果が得られる。 Also, when the lid is opened, the door piece is opened by rotating the locking member having a knob protruding around the watch body to release the urging force of the pivot portion, and when the lid is closed, the opened door piece is opposed to the urging force. Since the cover is pressed in the dial direction and locked to the locking member, an effect that the lid can be easily opened and closed by hand can be obtained.

　また、開蓋時には２枚の扉片が文字盤に対して垂直状態となり、文字盤上に形成した模様が現れるようにしたため、意匠的美観を増大させるという効果が得られる。 (4) Further, when the lid is opened, the two door pieces are perpendicular to the dial, and the pattern formed on the dial appears so that the effect of increasing the design appearance can be obtained.

　また、時計本体周囲に突出したつまみにはその端面部に滑り止めが施されているため、端部に手を当てても滑ることなく回転させることができるという効果が得られる。ため In addition, since the knob protruding around the watch body is provided with a non-slip surface at the end face, an effect is obtained that the knob can be rotated without slipping even if the hand is put on the end.

　この考案の好ましい実施の形態を、以下に説明する。この考案の開閉式時計は、時計本体の時刻を表示する文字盤と、該文字盤を前方で覆う蓋体とを有し、その蓋体を開閉自在とした腕時計であって、文字盤の周縁部には少なくとも２枚の扉片をそれぞれ対向させて枢着し、開蓋時には２枚の扉片を付勢力により文字盤から離隔させて全開状態にすることで文字盤上に形成した模様を現し、閉蓋時には２枚の扉片を付勢力に逆らって全閉状態にすることで蓋体の表面上に形成した模様を現すようになっている。好ましい A preferred embodiment of the present invention will be described below. The openable / closable timepiece of the present invention is a wristwatch having a dial for displaying the time of the watch body, and a lid for covering the dial in front, wherein the lid is freely openable and closable. At least two door pieces are pivotally attached to the part so as to face each other, and when the lid is opened, the two door pieces are separated from the dial by the urging force to make the pattern formed on the dial fully open. When the lid is closed, the two door pieces are fully closed against the urging force, so that a pattern formed on the surface of the lid is displayed.

　扉片は互いに閉じたときに文字盤の蓋体となり、互いに重なり合う部分がないようになっている。また、開蓋時には時計本体周囲に突出したつまみを有する係止部材を回転させて前記枢着部の付勢力を解放することにより扉片を開き、閉蓋時には開いた扉片を付勢力に逆らって文字盤方向に押付けて係止部材に係止させるようになっている。そして、時計本体周囲に突出したつまみにはその端面部に滑り止めが施されている。 The door pieces become the cover of the dial when closed, so that there are no overlapping parts. When the lid is opened, the locking member having a knob protruding around the timepiece body is rotated to release the urging force of the pivot portion to open the door piece, and when the lid is closed, the opened door piece is opposed to the urging force. The dial is pressed in the direction of the dial to lock the locking member. The knob protruding around the timepiece body is provided with a non-slip end face.

FIG. 7 is a perspective view showing a detailed structure of an engaging portion added to the locking portion shown in FIG.

　これらの図を参照しながら、まず本考案である開閉式時計の構成を説明すると、図１に示すように、開閉式時計本体１は、時計本体４と、時刻合わせ等のリューズ２と、時刻を示す文字盤３と、該文字盤３を覆い蓋体になる扉片１５、１６および時計バンド６等とからなり、扉片１５、１６は時計本体１の周縁部に枢着されている。そして、その枢着部にはばね１１が備えられ、そのばね１１によって扉片１５、１６が全閉方向に付勢力を受けつつ取付られている。 With reference to these figures, the structure of the openable timepiece according to the present invention will be described first. As shown in FIG. 1, the openable timepiece body 1 includes a watch body 4, a crown 2 for time setting and the like, and a timepiece. , And door pieces 15 and 16 and a watch band 6 which cover the dial 3 and serve as a cover. The door pieces 15 and 16 are pivotally attached to the periphery of the watch body 1. The pivot portion is provided with a spring 11, and the door pieces 15 and 16 are attached by the spring 11 while receiving a biasing force in the fully closing direction.

　さらに開閉式時計本体１には、図２に示すように、ドーナッツ状部材の支持板５および回転板７がそのドーナッツ状部材の中心に文字盤３を設置しつつ順次組込まれている。 (2) Further, as shown in FIG. 2, a support plate 5 and a rotary plate 7 of a donut-shaped member are sequentially incorporated in the openable / closable watch main body 1 with the dial 3 installed at the center of the donut-shaped member.

　支持板５は図５に示したように両サイドに切欠部８を有し、ドーナッツ状部材の周囲の上下箇所に係止孔７ａ、７ｂを有している。この切欠部８は時計本体４に組込んだ際に扉片１５、１６の枢着部に当たらないように逃げを設けたものであり、係止孔７ａ、７ｂは後述する扉片１５、１６に形成されている係合部１５ａ、１６ｂがそれぞれ嵌着するための孔である。 (5) The support plate 5 has notches 8 on both sides as shown in FIG. 5, and has locking holes 7a and 7b at upper and lower positions around the donut-shaped member. The cutout 8 is provided with a relief so as not to hit the pivotal portions of the door pieces 15 and 16 when the notch 8 is incorporated in the watch body 4, and the locking holes 7a and 7b are provided with door pieces 15 and 16 to be described later. Are holes into which the engaging portions 15a and 16b formed in the holes are fitted.

　次に、時計本体４の内側に位置する回転板７は図６に示したように前述した支持板５と同様に両サイドに切欠部９を有しており、この切欠部９は支持板５に形成した切欠部８より大きく切欠されている。その理由としては、図２に示したように時計本体４に組込んだ際に扉片１５、１６の枢着部を解放するものであるが、後述するようにこの回転板７は扉片１５、１６を開閉するためのつまみとなり、そのつまみを回転させてスイッチとして動作させる必要があるために、スイッチ動作のストロークを設けているためである。そしてまた、図６に示したように回転板７のドーナッツ状部材周囲面上下箇所に係止孔１０ａ、１０ｂを有している。この係止孔１０ａ、１０ｂ内にはそれぞれ凹部１２ａ、１２ｂが形成されており、この凹部１２ａ、１２ｂには後述する扉片１５、１６に形成されている係合部１５ａ、１６ｂがそれぞれ対応し係止される。 Next, as shown in FIG. 6, the rotary plate 7 located inside the watch main body 4 has cutouts 9 on both sides similarly to the support plate 5 described above. The cutout is larger than the cutout 8 formed at the bottom. The reason for this is that the pivotal portions of the door pieces 15 and 16 are released when the door piece 15 and 16 are assembled into the timepiece body 4 as shown in FIG. , 16 to open and close, and it is necessary to rotate the knob to operate as a switch, so that a switch operation stroke is provided. Further, as shown in FIG. 6, the rotating plate 7 has locking holes 10a and 10b at upper and lower positions on the peripheral surface of the donut-shaped member. Recesses 12a, 12b are formed in the locking holes 10a, 10b, respectively. Engaging portions 15a, 16b formed on door pieces 15, 16 described later correspond to the recesses 12a, 12b, respectively. Locked.

　次に、本考案の開閉式時計本体１に取付られた扉片１５、１６の開閉動作を説明する。 Next, the opening and closing operation of the door pieces 15 and 16 attached to the openable / closable watch main body 1 of the present invention will be described.

　この一実施例では、扉片１５、１６は互いに対称的な大きさに形成されており、この表面には模様が形成されている。そして、全閉した状態では図３に示したように、文字盤３上で左右の扉片１５、１６は重なる部分はなく、その形状自体が互いには嵌るように面一状態になり、扉片１５、１６の表面に形成した模様を見ることができる。 In this embodiment, the door pieces 15 and 16 are formed in symmetrical sizes, and a pattern is formed on the surface thereof. In the fully closed state, as shown in FIG. 3, the left and right door pieces 15 and 16 on the dial 3 have no overlapping portions, and are flush with each other so that their shapes fit together. The patterns formed on the surfaces of Nos. 15 and 16 can be seen.

　また、扉片１５、１６が全開した状態では、図２に示したように、それぞれ文字盤３に対して垂直方向に開くので、文字盤３が図２に示したように現れ、文字盤３内に形成した模様を見ることができる。 In the state where the door pieces 15 and 16 are fully opened, as shown in FIG. 2, each of the dials opens in a direction perpendicular to the dial 3, so that the dial 3 appears as shown in FIG. You can see the pattern formed inside.

　このように開閉する扉片１５、１６は、ばね１１によって時計本体４に枢着され、常に開く方向に付勢力が働いている。つまり、開蓋時にはこの付勢力を解放し、逆に閉蓋時には付勢力をかけるようにする。このばね１１の付勢力を制御するスイッチとなるのは、扉片１５および扉片１６に形成されてある係合部１５ａおよび係合部１６ｂが、支持板５に形成してある係止孔７ａおよび７ｂを貫いて、回転板７に形成してある係止部１０ａおよび１０ｂに係止する係止部で行われる。扉 The door pieces 15 and 16 that open and close in this manner are pivotally attached to the timepiece body 4 by the springs 11, and a biasing force is constantly applied in the opening direction. That is, the urging force is released when the lid is opened, and the urging force is applied when the lid is closed. The switch for controlling the biasing force of the spring 11 is formed by engaging portions 15a and 16b formed on the door piece 15 and the door piece 16 with locking holes 7a formed on the support plate 5. And 7b, and is stopped by locking portions 10a and 10b formed on the rotating plate 7.

　回転板７と支持板５はドーナツ状部材の中心部に形成した大きな孔を中心にして、切欠部９および切欠部８それに係止部１０ａおよび１０ｂをそれぞれ合わせつつ順次時計本体４に組入れて固定する。このように固定することで図２に示したように、係止孔７ａおよび係止孔７ｂ内には、それぞれ係止部１０ａおよび係止部１０ｂの一部分が見えるように設置される。 The rotating plate 7 and the supporting plate 5 are assembled and fixed in the timepiece main body 4 sequentially around the large hole formed in the center of the donut-shaped member, while aligning the notch 9, the notch 8, and the locking portions 10a and 10b respectively. I do. By fixing in this manner, as shown in FIG. 2, the locking portions 10 a and 10 b are respectively installed in the locking holes 7 a and 7 b so as to be visible.

　次に、扉片１５，１６の裏面側に設置してある係合部１５ａ、１６ｂについての説明をする。両者は同一形状で且つ同一の動作をするものなので、本説明では扉片１５の動作のみを説明し、扉片１６の動作説明は省略する。扉片１５の裏面側に形成されている係合部１５ａは図７に示すように、中央部が切欠された円柱状を成しており、取付面１５ａ−１が扉片１５の裏面に接着剤等によって取付られている。その取付面から切欠され延出された基部１５ａ−２が形成されており、その基部１５ａ−２の先端方向には円柱状の係合部材１５ａ−３が形成されている。そして、係合部材１５ａ-３の頭部１５ａ−４は円錐状のテーパを有している。この円柱状の係合部１５ａの軸と直角に切断した断面の直径は支持板５の係止孔７ａより略小さいく形成されているので、係合部１５ａの係合部材１５ａ−３は係止孔７ａに嵌合されるようになっている。 Next, the engagement portions 15a and 16b provided on the back surfaces of the door pieces 15 and 16 will be described. Since both have the same shape and perform the same operation, only the operation of the door piece 15 will be described in this description, and the operation description of the door piece 16 will be omitted. As shown in FIG. 7, the engaging portion 15 a formed on the back surface side of the door piece 15 has a columnar shape with a notched center portion, and the mounting surface 15 a-1 is bonded to the back surface of the door piece 15. It is attached by an agent or the like. A base 15a-2 which is notched and extended from the mounting surface is formed, and a columnar engaging member 15a-3 is formed in a direction of the tip of the base 15a-2. The head 15a-4 of the engaging member 15a-3 has a conical taper. Since the diameter of the cross section of the columnar engaging portion 15a cut at right angles to the axis is formed to be substantially smaller than the engaging hole 7a of the support plate 5, the engaging member 15a-3 of the engaging portion 15a is engaged. It is adapted to be fitted into the stop hole 7a.

　また、係合部材１５ａ−３が係止孔７ａに嵌合されると共に係止部１０ａにも嵌合されることになるが、その際に、基部１５ａ−２は係止部１０ａの凹部１２ａ内に嵌り込み係合部材１５ａ−３の係合面１５ａ−５が係止孔７ａに引っ掛かかるように係止される。 In addition, the engaging member 15a-3 is fitted into the locking hole 7a and also into the locking portion 10a. At this time, the base 15a-2 is fitted into the concave portion 12a of the locking portion 10a. The engagement surface 15a-5 of the engagement member 15a-3 is engaged so as to be hooked on the engagement hole 7a.

　その係合面１５ａ−５が係止孔７ａに引っ掛かかる動作を更に詳しく説明すると、まず、時計本体４に固定されている支持板５の内側に位置する回転板７は図２に示した状態つまり、係止部１０ａに形成した凹部１２ａの底面部を係止孔７ａの内周縁部に略接するように設置するが、このとき、この位置から所定の移動量を常に右回転力の図示しないばねの付勢力がかかるようにしておく。つまり、その頭部がテーパ状に形成されている頭部１５ａ−４は係止孔７ａを貫き係止部１０ａおよび凹部１２ａに到達し、さらにこの状態から押込むことによって、頭部１５ａ−４のテーパ部が係止部１０ａおよび凹部１２ａの内周端部に接しながら進んで行くので、その進みに従い回転板７は付勢力に逆らいながら回転方向Ａに基部１５ａ−２が凹部１２ａに嵌るまで回転移動し、基部１５ａ−２が凹部１２ａに嵌ると今度は回転板７は基部１５ａ−２の厚み寸法まで回転が戻され、係合部１５ａは係止部１０ａに係止されることになる。同様に係合部１６ｂも係止部１０ｂに係止される。 The operation in which the engagement surface 15a-5 is hooked on the locking hole 7a will be described in more detail. First, the rotary plate 7 located inside the support plate 5 fixed to the timepiece body 4 is shown in FIG. In this state, the bottom surface of the concave portion 12a formed in the locking portion 10a is installed so as to be substantially in contact with the inner peripheral edge of the locking hole 7a. The biasing force of the spring should not be applied. That is, the head 15a-4 whose head is formed in a tapered shape penetrates through the locking hole 7a and reaches the locking portion 10a and the concave portion 12a. The tapered portion advances while being in contact with the locking portion 10a and the inner peripheral end of the concave portion 12a. As the taper portion advances, the rotating plate 7 moves against the urging force until the base portion 15a-2 fits into the concave portion 12a in the rotation direction A. When the base plate 15a-2 rotates and moves and the base 15a-2 fits into the concave portion 12a, the rotation of the rotary plate 7 is returned to the thickness of the base 15a-2, and the engaging portion 15a is locked by the locking portion 10a. . Similarly, the engaging portion 16b is also locked by the locking portion 10b.

　このような状態で支持板５と回転板７とが組合わされているので、扉片１５および扉片１６は、それぞれ係合部１５ａおよび１６ｂを係止部１０ａおよび１０ｂに対応するように形成しておくことで、扉片１５および扉片１６を閉じる時は、それぞれ文字盤３方向へ押付ければ良い。 Since the supporting plate 5 and the rotating plate 7 are combined in such a state, the door pieces 15 and 16 have the engaging portions 15a and 16b formed so as to correspond to the locking portions 10a and 10b, respectively. Thus, when closing the door piece 15 and the door piece 16, they may be pressed toward the dial 3 respectively.

　また、今度は逆に扉片１５および扉片１６を開く時は、回転板７を回転方向Ａの方向に回転させることで、基部１５Ａ−２が凹部１２ａから外れると共に係合面１５ａ−５が係止部１０ａの内周縁部から外れるので、扉片１５および扉片１６はばね１１の付勢力から解放されて開かれることになる。 Also, when the door piece 15 and the door piece 16 are to be opened, the rotating plate 7 is rotated in the direction of the rotation direction A, so that the base 15A-2 is disengaged from the concave portion 12a and the engaging surface 15a-5 is opened. The door piece 15 and the door piece 16 are released from the biasing force of the spring 11 and are opened because they come off the inner peripheral edge of the locking portion 10a.
